    DIAZ, Circuit Judge:
    Daryl Van Donk challenges a condition of his supervised release requiring him to
    comply with the rules of his sex-offender treatment program, which ban him from viewing
    any materials that sexually arouse him. He argues that this ban is too restrictive to comport
    with 
    18 U.S.C. § 3583
    (d), is unconstitutionally overbroad and vague, and is an
    impermissible delegation of the court’s duty to impose conditions of supervised release.
    We disagree. The ban is permissible under § 3583(d) and isn’t overbroad because
    the district court made an individualized assessment, based on the testimony of Van Donk’s
    treatment provider, that it was necessary. It’s enforced in a way that avoids the issues with
    which the vagueness doctrine is concerned. And it’s not an impermissible delegation
    because only the district court will decide whether Van Donk violated his conditions of
    release. We thus affirm the release condition imposed by the district court. 1
    I.
    This case has a long procedural history involving several supervised-release
    revocation proceedings. We begin by summarizing it.
    A.
    Van Donk was convicted in 2008 of possessing more than 600 images of child
    pornography and sentenced to eighty months in prison, followed by five years of
    1
    Some of the materials in the factual record were submitted under seal. At oral
    argument, Van Donk moved to unseal them. We grant that motion, as discussing those
    materials is necessary to explain our decision in this case.
    3
    supervised release. The district court imposed thirteen standard conditions of supervised
    release, as well as eleven special conditions tailored to child-pornography offenders. One
    of these special conditions was that Van Donk participate in a sex-offender treatment
    program of his probation officer’s choosing. Another condition was that Van Donk not
    possess any material depicting adults or minors “engaged in sexually explicit conduct, as
    defined by 
    18 U.S.C. § 2256
    (2).” 2 S.J.A 133.
    Sometime after Van Donk’s release, his probation officer discovered that he had
    child pornography at his mother’s house. He admitted to viewing these images and to
    visiting a Goodwill store to view pornography on its computers. The district court revoked
    Van Donk’s supervised release and sentenced him to another twelve months in prison
    followed by three years of supervised release.
    Van Donk was released again in November 2015, completed a ten-month intensive
    inpatient sex-offender treatment program in Minnesota, and then returned to his Virginia
    home. At his probation officer’s direction, he entered an outpatient sex-offender treatment
    program run by Vicki Cash Graff, a clinical social worker.
    2
    Subsection 2256(2) defines “‘sexually explicit conduct’” as “actual or simulated—
    (i) sexual intercourse, including genital-genital, oral-genital, anal-genital, or
    oral-anal, whether between persons of the same or opposite sex;
    (ii) bestiality;
    (iii) masturbation;
    (iv) sadistic or masochistic abuse; or
    (v) lascivious exhibition of the anus, genitals, or pubic area of any person.”
    
    18 U.S.C. § 2256
    (2)(A).
    4
    During an unannounced search in May 2017, a probation officer found two hundred
    sexually explicit DVDs at Van Donk’s residence.           Police officers found no child
    pornography on these DVDs, however. His probation officer verbally reprimanded him
    and advised that he was now on a zero-tolerance policy.
    In May 2018, Van Donk failed a polygraph examination (administered by his
    probation officer) regarding whether he had viewed pornography. He then admitted to
    “having watched a shower scene between two females ages 8–10” on a Spanish cable
    channel. J.A. 90. A subsequent search of Van Donk’s home uncovered sixteen DVDs and
    a cell phone containing pornography. Some of the DVDs purported to depict juveniles,
    although police couldn’t determine whether the individuals therein were minors.
    Additionally, the probation officer found a handwritten list of pornographic films and
    individuals depicted therein on his bedside table, some of whose titles referenced juvenile
    girls. Van Donk explained to the officer that he wrote these titles down so he could
    remember them after his period of supervision was over. The officer then petitioned to
    revoke Van Donk’s supervised release.
    B.
    The district court held a revocation hearing in October 2018. Van Donk’s probation
    officer testified as to the pornographic materials found at Van Donk’s home. The officer
    also cited a report from Graff, who was still supervising Van Donk’s treatment. Graff’s
    report indicated that Van Donk “was no longer receptive to any type of treatment services”
    and was “riding out the remainder of his period of supervision.” S.J.A 158.
    5
    Van Donk offered letters from several people about the progress that he had made,
    including his supervisor from the Minnesota inpatient treatment program he had attended
    two years earlier. That supervisor opined that it was healthy for Van Donk to use
    pornography to “bridge arousal to adult targets.” J.A. 92. He noted, though, that Van Donk
    “had a history of using sexually explicit material to cope with life” and that if he was
    continuing to do that, it would be problematic. J.A. 93. Van Donk’s counsel conceded
    that he had violated his conditions of release, but asked that he be treated leniently because
    he was only caught with adult pornography and because he was understandably tired of
    going through Graff’s intense program.
    The district court sentenced Van Donk to six more months in prison and eighteen
    months of supervised release, a sentence within the applicable Federal Sentencing
    Guidelines. The court said that it was “reaffirming each and every one of the conditions
    we have imposed” after Van Donk’s revocation, S.J.A. 188, and then announced:
    I have said, and I have made as clear as I can, an individual assessment that
    this gentleman cannot possess pornography of any kind because he cannot
    be constrained from straying from sexually explicit conduct into the area of
    child pornography. He’s just done it time and time again and for that reason,
    I find and I conclude that I believe that this condition of no sexually explicit
    material . . . is appropriate for his specific circumstances . . . .
    No pornography for Mr. Vandonk [sic]. I have made my individual
    assessment based on his own conduct and his inability to stay away from
    images involving or portraying children involved in sex.
    S.J.A 191–92.
    Despite stating that it was reaffirming the prior conditions, the court reworded some
    of them without explaining why. The court replaced the earlier condition banning sexually
    6
    explicit materials with one stating that Van Donk “shall not possess, view or otherwise use
    any type of pornography, to include adult, juvenile or child pornography, or pornography
    that depicts juveniles.” J.A. 36. Another new condition—the one at issue in this appeal—
    was that Van Donk submit to sex-offender treatment and “abide by all rules, requirements,
    and conditions imposed by the treatment provider until discharged from treatment by the
    provider.” J.A. 34.
    Van Donk appealed, challenging the condition that he not use “any type of
    pornography” as overbroad and unconstitutionally vague. The government conceded that
    a ban on “pornography,” without further definition, might be too vague. The government
    thus moved to remand to the district court, asserting that the condition should, as it did
    before, ban depictions of sexually explicit conduct as defined by 
    18 U.S.C. § 2256
    (2). We
    granted the government’s motion. In the meantime, Van Donk was released from prison
    in May 2019 and re-entered Graff’s outpatient program.
    C.
    The district court held a hearing on the condition banning pornography in July 2019,
    at which Graff testified. She has been a certified sex-offender treatment provider for nearly
    thirty years. Graff initially prohibits all of her patients from viewing sexually explicit
    materials, but she had been working with Van Donk long enough to see that this prohibition
    was especially needed for him.
    A goal of Graff’s program is for patients to develop healthy sexual relationships,
    and she thought “pornography serves as a barrier” to Van Donk’s “engaging in contact
    with age-appropriate partners.” J.A. 98–99. She posited that Van Donk was addicted to
    7
    pornography and, because Van Donk was aroused by both adult and juvenile females, she
    feared that “would eventually lead to child porn.” J.A. 99. She also believed that his prior
    treatment program, which used pornography to try to limit his arousal to adults, was
    unsuccessful.
    Graff expected Van Donk to remain in her program for the full eighteen months of
    his supervised release. She wouldn’t allow Van Donk to view pornography at any point in
    the program and didn’t think he should ever view it for the rest of his life. In fact, she
    suggested that pornography “isn’t healthy” for anyone. J.A. 103.
    Graff also explained that her program’s definition of “pornography” extended to
    mainstream media (like movies or advertisements) that sexually aroused Van Donk. In her
    view, if Van Donk were to see anything that aroused him enough that he wanted to view it
    again or masturbate to it—even a scene in a mainstream movie or a television show—he
    should report it to Graff and then not access it again. Graff stated that a relationship with
    a peer-aged woman would be a sign of progress for Van Donk.
    Van Donk’s counsel argued that the pornography ban Graff described was
    overbroad and vague, and that the court shouldn’t be enforcing rules meant to help Van
    Donk have healthy relationships because that is beyond the scope of supervised release.
    While crediting Graff’s testimony that adult pornography could be a gateway to child
    pornography, the district court agreed with Van Donk that its prior ban on any type of
    pornography “might technically be overbroad” and replaced it with a ban on child
    8
    pornography. 3 J.A. 123. But the court noted that another condition of release, which would
    remain in place, required Van Donk to comply with his treatment provider’s rules. If Van
    Donk was kicked out of treatment because he broke Graff’s rules—including her ban on
    materials that arouse him (her “pornography ban”)—he would violate his terms of
    supervised release.     The court explained that it shouldn’t “micromanage treatment
    protocols.” J.A. 124.
    The district court promptly filed a written order explaining its findings. Therein,
    the court summarized Graff’s testimony about why Van Donk shouldn’t use adult
    pornography and reiterated that Van Donk must comply with all of Graff’s rules. Based
    on Graff’s testimony, the court
    remain[ed] convinced that defendant’s successful completion of sex offender
    treatment designed to promote healthy relationships and prevent the return to
    the illegal use of child pornography requires him to follow the treatment
    protocols established by his sex offender treatment counselor, including [her
    pornography ban].
    J.A. 69.
    Van Donk then appealed, challenging the condition that requires him to follow
    Graff’s rules, including her pornography ban.
    D.
    In October 2019, while this appeal was pending, Van Donk’s probation officer
    petitioned the district court to revoke his supervised release. The officer alleged that Van
    3
    This condition now reads: “[T]he defendant shall not possess any material that
    depicts child pornography or minors engaged in sexually explicit conduct as defined in 18
    [U.S.C. §] 2256(2).” J.A. 121.
    9
    Donk had violated the conditions that he answer the officer’s questions truthfully, that he
    follow the officer’s instructions as to the conditions, and that he follow his treatment
    provider’s rules.   As a result, Graff had discharged Van Donk from her program.
    According to the petition, Van Donk admitted to the officer that he had purchased, viewed,
    and destroyed about one or two dozen adult-pornographic movies. One of the movies, he
    admitted, may have contained a juvenile girl taking a shower.
    A few days later, Van Donk appeared in court to respond to the petition, and the
    magistrate judge released him on a personal recognizance bond. The magistrate judge
    added two new conditions of release, banning Van Donk from using Internet-capable
    devices without the court’s prior approval and ordering that he disclose all such devices to
    which he has access. Van Donk then moved to amend these conditions. He informed the
    court that he was trying to find a treatment provider other than Graff, but to the extent that
    a new provider would ban him from viewing adult pornography, he maintained his
    objection to such a ban being enforced by the court for the reasons stated in his appeal.
    Shortly thereafter, Van Donk reported to his probation officer that he had recently
    viewed pornography and had either entered a sex shop or used sex-related phone services.
    An officer then visited Van Donk at his home, where Van Donk admitted accessing the
    Internet on his phone for the past three weeks and viewing adult pornography. A scan of
    the phone revealed adult pornography. The officer filed this new information with the
    court, alleging that Van Donk had violated the condition that he immediately disclose any
    Internet-capable devices to which he had access.
    10
    The district court promptly held a supervised-release revocation hearing. Graff and
    Van Donk’s probation officer testified. Graff stated that she and Van Donk had met once
    a week while he was in the program and had discussed her pornography ban each time.
    She defined “pornography” for Van Donk as any materials that gave him an erection, and
    stated that
    if he happened upon images in mainstream movies that made him have an
    erection, we would discuss it. And many times that would be okay. The part
    that would make it not okay would be if he began seeking out that same
    movie over and over and over. But having it occur in a movie that he had no
    idea would have something like that in it was fine and even encouraging at
    times.
    Feb. 3, 2020 Revocation Hr’g Tr. 12:11–15, ECF No. 57-8. She also said that Van Donk
    was frustrated by not being allowed to watch pornography, but never seemed confused
    about what materials she forbade or asked whether a particular image was acceptable.
    After he had been in her program for five months, Graff learned from Van Donk’s
    probation officer that he had frequently been viewing pornography, and she confronted him
    about it. After he admitted it to her, she expelled him from her program.
    The probation officer testified that Van Donk (1) never expressed confusion to her
    about what fell under Graff’s ban; (2) had ordered, viewed, and then destroyed dozens of
    explicit pornographic videos, some of which purported to depict juveniles; (3) initially lied
    about this to his probation officer; (4) activated his cell phone to connect to the Internet;
    and (5) bought a laptop without telling his probation officer.
    The district court concluded that Van Donk had violated the following five
    conditions of release:
    11
    Standard Condition 4: “You must answer truthfully the questions asked by
    your probation officer.”
    Standard Condition 13: “You must follow the instructions of the probation
    officer related to the conditions of supervision.”
    Special Condition 6: “The defendant must abide by all rules, requirements,
    and conditions imposed by the treatment provider until discharged from
    treatment by the provider.”
    Special Condition 7: “. . . The defendant may not purchase, possess, or use
    any computer . . . cellular telephone, or other Internet-capable device,
    without the prior approval of the court, upon consultation with the probation
    officer.”
    Special Condition 8: “The defendant must immediately disclose to the
    probation officer all computer devices, cellular telephones, or Internet-
    capable devices to which the defendant has access.”
    See Gov’t Feb. 11, 2020 Resp. Letter 1–2, ECF No. 56.
    On that basis, the court revoked Van Donk’s supervised release, sentencing him to
    nine more months in prison and another year of supervised release, with the same
    conditions in place. The court expressed its frustration with Van Donk’s lies and his
    disregard for its orders. The court also reaffirmed its finding, based on Graff’s testimony,
    that Van Donk should be prohibited from viewing pornography.
    Van Donk filed a new appeal, which we consolidated with his previous appeal,
    challenging Special Condition 6 to the extent it forbids him to view pornography. While
    Van Donk is currently in prison and not in Graff’s program, he contends (and we agree)
    that his appeal remains ripe because he is serving a sentence based in part on a violation of
    Graff’s rules, and because he may rejoin Graff’s program when he is released. Graff is the
    only sex-offender treatment provider in the Harrisonburg, Virginia area under contract with
    the United States Probation Office.
    12
    We proceed to consider whether Special Condition 6, to the extent it required and
    may continue to require Van Donk to follow Graff’s pornography ban, is proper.
    II.
    We review special conditions of supervision for abuse of discretion, recognizing
    that district courts have “broad latitude” in this space. United States v. Dotson, 
    324 F.3d 256
    , 260 (4th Cir. 2003). “A district court by definition abuses its discretion when it makes
    an error of law,” In re Grand Jury Subpoena, 
    870 F.3d 312
    , 316 (4th Cir. 2017) (cleaned
    up), such as by violating a constitutional right.
    Van Donk argues that the condition mandating that he abide by his treatment
    provider’s rules—in particular, Graff’s pornography ban—was an abuse of discretion, for
    three reasons. We address each in turn.
    A.
    First, Van Donk contends that because the district court ordered that he follow the
    treatment provider’s rules, those rules are subject to 
    18 U.S.C. § 3583
    (d), which
    requires that special conditions of supervised release be: (1) “reasonably
    related” to the statutory goals of deterrence, protection of the public, and
    rehabilitation; (2) “no greater [a] deprivation of liberty than is reasonably
    necessary” to achieve those statutory goals; and (3) consistent with any
    relevant policy statements issued by the Sentencing Commission.
    United States v. McMiller, 
    954 F.3d 670
    , 676 (4th Cir. 2020) (alteration in original)
    (quoting 
    18 U.S.C. § 3583
    (d)). In his view, Graff’s pornography ban doesn’t comport with
    § 3583(d) because it’s more restrictive than is necessary to serve the purposes of supervised
    release.
    13
    We agree with Van Donk that § 3583(d) applies to the pornography ban. We have
    previously regarded treatment protocols as subject to § 3583(d) where the district court
    expressly authorized (but didn’t order) the defendant’s treatment provider to use them. See
    Dotson, 
    324 F.3d at
    260–61 (authorizing a defendant’s sex-offender treatment provider to
    use polygraph and penile plethysmograph testing on the basis that such tests were
    “reasonably related” to the purposes of supervised release (quoting 
    18 U.S.C. § 3583
    (d)(1)); see also United States v. Behren, 
    65 F. Supp. 3d 1140
    , 1148 (D. Colo. 2014)
    (viewing “the requirements of the [sex-offender treatment] program as being, in effect,
    conditions of supervised release”).
    We take the same tack here, where the district court made findings to support Graff’s
    pornography ban and stated that Van Donk’s release could be revoked if he was expelled
    from Graff’s program for violating the ban. The district court’s authority to impose special
    conditions comes from § 3583(d), so it would be wrong for the court to enforce a rule that
    ventures beyond the statute’s requirements. Treatment providers shouldn’t be able to
    compel patients to do things wholly unrelated to the purposes of supervised release—e.g.,
    learn to ride a unicycle—under threat of the court revoking the patient’s release.
    We don’t believe, however, that Graff’s pornography ban runs afoul of § 3583(d).
    A sentencing court must provide an individualized explanation for why any special
    conditions it imposes are appropriate in light of the § 3583(d) factors. McMiller, 954 F.3d
    at 676–77. The amount of explanation required “will vary with the nature of the condition
    imposed and the circumstances of each case.” Id. at 677. An inadequate explanation is
    cause for remand. See id.
    14
    Restrictions on otherwise legal pornography are permissible under § 3583(d) where
    the district court adequately explains why they are appropriate, and the record supports
    such a finding. See United States v. Lord, 393 F. App’x 60, 63 (4th Cir. 2010) (per curiam)
    (upholding a ban on any “sexually explicit materials” on plain error review); United States
    v. Henson, 22 F. App’x 107, 112 (4th Cir. 2001) (per curiam) (upholding an analogous ban
    “[i]n light of Henson’s conviction for receiving more than 100 images of child pornography
    and his prior conviction for taking indecent liberties with a minor”). For example, other
    circuits have upheld bans on adult pornography where a treatment provider testified that
    sexually stimulating images could cause the defendant to revert to accessing child
    pornography, see United States v. Brigham, 
    569 F.3d 220
    , 232–34 (5th Cir. 2009); where
    the defendant had often videotaped his sexual assaults, leading the district court to find a
    connection between pornography and his criminal behavior, see United States v.
    Simmons, 
    343 F.3d 72
    , 81–83 (2d Cir. 2003); and where a probation officer believed that
    such a ban was needed to address the defendant’s deviant sexual behavior triggered by his
    alcohol abuse, see United States v. Bee, 
    162 F.3d 1232
    , 1234–35 (9th Cir. 1998).
    In contrast, appellate courts have struck down such conditions when they were
    unaccompanied by individualized explanations for their broad sweep. Indeed, we recently
    vacated a ban on sexually explicit materials because the district court’s only explanation
    for it was that it’s “a standard condition for sex offenders” and “necessary and appropriate
    under the circumstances.” See United States v. Wroblewski, 781 F. App’x 158, 162–63
    (4th Cir. 2019) (per curiam); see also United States v. Armel, 
    585 F.3d 182
    , 186 (4th Cir.
    2009); United States v. Eaglin, 
    913 F.3d 88
    , 99–101 (2d Cir. 2019) (collecting cases
    15
    “finding an adult pornography ban to be more restrictive than necessary to achieve the
    goals of sentencing where there is little indication that access to such material will impede
    a defendant’s rehabilitation or put the community at risk”).
    Here, the district court credited Graff’s testimony that her pornography ban is meant
    to keep Van Donk from recidivating and to treat his pornography addiction. According to
    Graff, adult pornography and other sexually stimulating images could serve as a gateway
    to child pornography for Van Donk, and his addiction threatened to hinder his mental health
    and social relationships in the future. Graff based her opinion on her nearly thirty years of
    experience as a sex-offender treatment provider and her extensive dealings with Van Donk.
    And her concern about Van Donk’s addiction is corroborated by his previous treatment
    provider, who stated that it “could be problematic” for Van Donk to use pornography to
    “cope with his emotions.” J.A. 93.
    Based on this evidence, the district court found that Graff’s restriction on sexually
    stimulating material was necessary to treat Van Donk’s addiction and to deter him from
    future crimes. The court explained its finding at length in a written order and at multiple
    hearings. Treatment and deterrence are permissible purposes for conditions of release. See
    
    18 U.S.C. § 3583
    (d)(1) (citing 
    id.
     § 3553(a)(2)(B), (D)). Thus, the district court acted
    within its discretion by ordering Van Donk to follow Graff’s restriction.
    Van Donk’s counterarguments are unavailing. While he’s correct that Graff bans
    all of her new patients from accessing pornography, she testified (and the court found) that
    the ban was particularly needed in his case, satisfying the requirement that the district court
    make an individualized assessment as to each special condition. And while not every
    16
    treatment provider might share Graff’s negative view of pornography—i.e., her belief that
    it’s unhealthy for anyone—hers was the only expert testimony in this case, and her concern
    for Van Donk was corroborated by his prior treatment provider.
    B.
    Van Donk’s second argument is that Graff’s ban on sexually stimulating material,
    and thus Special Condition 6, is facially invalid because it is both unduly vague, in violation
    of the Fifth Amendment’s due process clause, and overbroad, in violation of the First
    Amendment’s free speech clause. We address his vagueness challenge first.
    1.
    A condition of supervised release is unconstitutionally vague if it doesn’t give a
    probationer “fair notice of the conduct that it punishes” or is “so standardless that it invites
    arbitrary enforcement.” Johnson v. United States, 
    135 S. Ct. 2551
    , 2556 (2015). In the
    case of a special condition banning “pornography” or “sexually stimulating material,” the
    relevant concerns are that a probationer might not know what items are forbidden and that
    a judge or probation officer could arbitrarily decide that an item is prohibited and therefore
    punish the probationer. See United States v. Guagliardo, 
    278 F.3d 868
    , 872 (9th Cir. 2002).
    Due to these risks, appellate courts have generally held that conditions banning
    “pornography” or “sexually stimulating materials,” without defining those terms, are
    unduly vague. See, e.g., United States v. Adkins, 
    743 F.3d 176
    , 194–95 (7th Cir. 2014)
    (vacating such a condition for vagueness and collecting other cases); Simmons, 
    343 F.3d at 82
     (noting that the term “pornography” is “inherently vague” and tying it to the definition
    contained in 
    18 U.S.C. § 2256
    (8) to cure the issue); United States v. Phipps, 
    319 F.3d 177
    ,
    17
    192–93 (5th Cir. 2003) (narrowing a ban on “sexually oriented or sexually stimulating
    materials” to refer only to the kind of materials available at “such places as strip clubs and
    adult theaters or bookstores”).
    Here, Graff forbade Van Donk from viewing any materials that gave him an
    erection. In the abstract, that’s a difficult standard to apply and enforce. Cf. Adkins, 743
    F.3d at 194 (“[H]ow can we tell which images . . . are sexually stimulating for Adkins?”).
    But Graff’s rule is different from the special conditions in the above-cited cases because it
    wasn’t imposed by the district court. Nor is it a static law that applies to a large group of
    people like a criminal statute, for which precision is especially important. It is instead a
    treatment protocol, subject to ongoing discussion between Van Donk and Graff and with a
    de facto scienter requirement.
    We think that this distinction is relevant to our analysis of Van Donk’s facial
    challenge. See Vill. of Hoffman Estates v. Flipside, Hoffman Estates, Inc., 
    455 U.S. 489
    ,
    498 (1982) (stating that the standard for vagueness shouldn’t be “mechanically applied”
    because “[t]he degree of vagueness that the Constitution tolerates . . . depends in part on
    the nature of the enactment”).      Evidence describing how Graff’s program operates,
    including that Van Donk wasn’t confused about what was prohibited, combined with the
    general rule that probationers may not be punished for inadvertent violations, satisfy us
    that there was no due process issue with ordering Van Donk to follow Graff’s rules. In
    short, the two concerns underlying the vagueness doctrine—inadequate notice and
    arbitrary enforcement—aren’t implicated here.
    18
    As to the first concern, Van Donk has never expressed uncertainty about what he
    could and couldn’t view, and he could have asked Graff for clarity at any time. Indeed,
    she encouraged him to do so. They had weekly meetings where they discussed the
    pornography ban. Vagueness issues are mitigated where the regulated party has “the ability
    to clarify the meaning of the regulation by its own inquiry.” See Vill. of Hoffman Estates,
    
    455 U.S. at 498
    . In contrast to Graff’s program, persons don’t have regular meetings with
    Congress or their sentencing judge to ask what statutes or release conditions mean.
    Graff also applied her rule in a way that protected Van Donk if he didn’t know that
    he was breaking it. For example, she asked that Van Donk report any incidents where he
    had been tempted to repeatedly view and masturbate to any particular video or image.
    When he did that, she didn’t expel him; rather, she told him not to access that video or
    image again. As Graff testified, her concern wasn’t that Van Donk would happen upon a
    sexually stimulating scene in a mainstream film or television show. It was that he would
    access visual materials for the purpose of getting sexually aroused. In essence, to violate
    Graff’s rule, Van Donk must specifically intend to do so. Taking that into account, Graff’s
    rule is clearer than an undefined ban on pornography or sexually stimulating materials.
    The hypotheticals that courts vacating pornography-ban release conditions have focused
    on—e.g., that a probationer will be imprisoned for admiring the artistic beauty of a
    Michelangelo sculpture, see United States v. Loy, 
    237 F.3d 251
    , 264 (3d Cir. 2001)—are
    not implicated here.
    For the same reasons, in assessing whether Van Donk broke Graff’s rule, the district
    court would not have to make arbitrary decisions about what counts as “sexually
    19
    stimulating.” It would only punish Van Donk if he purposely accesses materials for a
    reason that he knows is prohibited. A scienter requirement like this mitigates vagueness
    concerns. Vill. of Hoffman Estates, 
    455 U.S. at 499
    . And even if Graff accuses Van Donk
    of violating her rule, Van Donk would be able to explain to his probation officer—and
    ultimately to the court at a revocation hearing—that he lacked the requisite scienter to do
    so.
    We note also that Graff’s scienter requirement overlaps with the general rule that a
    district court may not revoke supervised release for “inadvertent violations,” United States
    v. Johnson, 
    446 F.3d 272
    , 281 (2d Cir. 2006) (citing Arciniega v. Freeman, 
    404 U.S. 4
    , 4
    (1971) (per curiam)); see also Bearden v. Georgia, 
    461 U.S. 660
    , 672–73 (1983) (holding
    that it will usually violate “the fundamental fairness required by” due process to imprison
    a probationer because he lacks the resources to pay a fine). Because of this scienter
    requirement, there’s no danger that Van Donk could commit an inadvertent violation.
    Graff’s rule admittedly leaves some gray areas. But conditions of release need not
    “describe every possible permutation, or spell out every last, self-evident detail.” Johnson,
    
    446 F.3d at 280
    . Van Donk had fair notice of what was forbidden: accessing materials for
    the purpose of getting sexually aroused. He could have asked for further clarity at any
    time. And given how Graff’s program functions, her rule’s scienter requirement, and the
    general rule against punishing inadvertent violations, there was little risk that Van Donk’s
    supervised release would be revoked arbitrarily. Relying on remote hypotheticals to vacate
    Graff’s pornography ban would let the tail wag the dog. Cf. Johnson, 
    135 S. Ct. at 2560
    (noting that “even clear laws produce close cases”).
    20
    The circumstances that led to Van Donk’s supervised release being revoked three
    times are instructive as to the minimal risk of arbitrary enforcement. Each time, Van Donk
    admitted to viewing dozens of pornographic videos. Two of these times, he initially lied
    to his probation officer about it. He has never expressed uncertainty about whether these
    videos were acceptable in Graff’s program. He knew that he was breaking her rule and
    kept doing it anyway. Only then was his supervised release revoked, and then only after
    being heard in the district court. The gray areas of Graff’s rule have not played a role in
    these revocations, and Van Donk has not explained why they are likely to do so in the
    future if he rejoins her program.
    If vagueness issues do arise, Van Donk may bring an as-applied challenge in
    revocation proceedings.     Contrary to what he argues, as-applied challenges are not
    inconsistent with United States v. Sanchez, 
    891 F.3d 535
     (4th Cir. 2018). There, we said
    that “a defendant may not challenge the special conditions of his original term of
    supervised release during later revocation proceedings.” 
    Id.
     at 539 (citing United States v.
    Johnson, 
    138 F.3d 115
    , 117–18 (4th Cir. 1998)). But that statement refers to facial
    challenges. An as-applied argument in a revocation proceeding doesn’t challenge the
    special condition’s facial validity, but rather its application to a particular act by the
    probationer. Cf. Farrell v. Burke, 
    449 F.3d 470
    , 486–94 (2d Cir. 2006) (Sotomayor, J.)
    (analyzing an as-applied vagueness challenge to a special condition banning pornography).
    We recognize that the Third and Ninth Circuits have stated that a supervised release
    condition banning “pornography” isn’t redeemed by the probationer’s ability to check with
    his probation officer. See Guagliardo, 
    278 F.3d at 872
    ; Loy, 
    237 F.3d at 266
    . Those courts
    21
    reasoned that, “without a more definitive standard to guide the probation officer’s
    discretion, there is a real danger that the prohibition on pornography may ultimately
    translate to a prohibition on whatever the officer personally finds titillating.” Loy, 
    237 F.3d at 266
    ; accord Guagliardo, 
    278 F.3d at 872
    . The Ninth Circuit was also troubled that “[a]
    probation officer could well interpret the term more strictly than intended by the court or
    understood by [the probationer].” Guagliardo, 
    278 F.3d at 872
    .
    This case is different. For starters, Graff isn’t barring anything that she personally
    “finds titillating.” She’s barring Van Donk from intentionally seeking out materials that
    arouse him. That’s the “more definitive standard” that was absent in the Third and Ninth
    Circuit cases. Also, unlike with the probation officers in those cases, the court is not asking
    Graff to interpret the court’s rule. Graff is using her own treatment protocol. Thus, there’s
    no risk of a disconnect between the rule’s creator and its interpreter—i.e., that Graff might
    tell Van Donk he can’t do something the court meant to allow, or vice versa.
    In sum, Graff’s ban on materials that arouse Van Donk comports with due process
    because it’s enforced in a way that avoids the issues with which the vagueness doctrine is
    concerned.
    2.
    We turn briefly to Van Donk’s overbreadth challenge. Graff’s pornography ban
    encompasses various materials that enjoy First Amendment protection. See United States
    v. Williams, 
    553 U.S. 285
    , 288 (2008) (indicating that, while obscenity and child
    pornography aren’t protected by the First Amendment, sexually explicit materials that have
    “social value” are). But that doesn’t make her ban unconstitutionally overbroad.
    22
    A condition of supervised release may restrict a probationer from engaging in what
    would otherwise be protected conduct, so long as the condition comports with 
    18 U.S.C. § 3583
    (d). Indeed, many typical conditions of release do this, like the one that forbids Van
    Donk from leaving his judicial district without permission.           The First Amendment
    overbreadth doctrine thus isn’t relevant in the context of a supervised-release condition that
    satisfies § 3583(d)’s requirements, like this one. See United States v. Albanese, 
    554 F.2d 543
    , 547 (2d Cir. 1977) (“Since, unlike a statute, the probation condition at issue here can
    affect only appellant, and since his conduct could be legitimately proscribed, it would be
    inappropriate for us to consider whether the condition might be overbroad on its face.”);
    cf. Adkins, 743 F.3d at 194–95 (collecting cases addressing vagueness and overbreadth
    challenges to conditions restricting access to sexually explicit materials, all of which
    focused on either vagueness or whether the restriction comported with § 3583(d)).
    We therefore reject Van Donk’s First Amendment overbreadth challenge.
    C.
    Lastly, Van Donk asserts that the district court improperly delegated a core judicial
    function—setting conditions of release—to Van Donk’s treatment provider. He is wrong.
    We agree with our sister circuits that it’s proper for a court to order a probationer to
    follow treatment-program rules. See United States v. Bender, 
    566 F.3d 748
    , 750, 752 (8th
    Cir. 2009) (affirming a condition requiring that the defendant “follow all other lifestyle
    restrictions or treatment requirements imposed by the therapist”); United States v. Fellows,
    
    157 F.3d 1197
    , 1204 (9th Cir. 1998) (same). Such a view comports with our recognition
    “that courts may use nonjudicial officers . . . to support judicial functions, as long as the
    23
    judicial officer retains and exercises ultimate responsibility.” United States v. Miller, 
    77 F.3d 71
    , 77 (4th Cir. 1996); accord United States v. Johnson, 
    48 F.3d 806
    , 808–09 (4th
    Cir. 1995).
    Of course, “the type of duty that the court may delegate is limited” by Article III.
    Johnson, 
    48 F.3d at
    808–09. A court can’t delegate “core judicial function[s]” such as the
    authority to decide the amount of a fine or restitution payment, Miller, 
    77 F.3d at 77
    , or
    whether a defendant must attend a treatment program, United States v. Melendez-Santana,
    
    353 F.3d 93
    , 101 (1st Cir. 2003), overruled on other grounds by United States v. Padilla,
    
    415 F.3d 211
     (1st Cir. 2005)); United States v. Peterson, 
    248 F.3d 79
    , 85 (2d Cir. 2001).
    But a court may delegate “details with respect to the selection and schedule of the
    program.” Peterson, 
    248 F.3d at 85
    .
    Similarly, while the court itself must be the one to order treatment, it may require a
    probationer to comply with the terms set forth by the treatment provider. See Bender, 
    566 F.3d at 752
    ; Fellows, 
    157 F.3d at
    1203–04; see also United States v. York, 
    357 F.3d 14
    ,
    21–22 (1st Cir. 2004) (affirming a requirement that the defendant submit to periodic
    polygraph testing “as a means to insure that he is in compliance with the requirements of
    his therapeutic program”).     Indeed, “[t]he court cannot be expected to design and
    implement the particularities of a treatment program.” Fellows, 
    157 F.3d at 1204
    .
    In Van Donk’s case, the district court retains ultimate responsibility over the core
    judicial function of deciding whether Van Donk has violated his conditions of supervised
    release. This is demonstrated by recent events: When Van Donk was expelled from Graff’s
    program, the court didn’t automatically revoke his supervised release, but rather ordered
    24
    hearings on the issue. This regime affords Van Donk due process without micromanaging
    his treatment.
    The cases Van Donk points to are either distinguishable or support our conclusion.
    In United States v. Myers, the Second Circuit recognized that courts don’t have to manage
    the details of a treatment program. See 
    426 F.3d 117
    , 130 (2d Cir. 2005) (citing Peterson,
    
    248 F.3d at 85
    ). As we have explained, United States v. Loy is distinguishable because,
    here, the court isn’t directing someone else to decide a difficult legal issue, i.e., to interpret
    a vague rule imposed by the court. Special Condition 6 authorizes the treatment provider
    to set and interpret its own rules, not to interpret the court’s rules. In United States v.
    Morin, the Fifth Circuit vacated a condition authorizing a therapist to impose, “without
    court review,” lifestyle restrictions that were unrelated to the defendant’s compliance with
    the treatment program. See 
    832 F.3d 513
    , 516–18 (5th Cir. 2016). In doing so, the court
    expressly distinguished conditions like the one we have before us now, stating that
    therapists may devise “the manner and means of therapy during a treatment program.” 
    Id.
    at 516–17. Finally, in United States v. Heckman, the Third Circuit vacated a condition that
    ordered the defendant to follow the probation office’s directions regarding contact with
    minors without cabining the office’s discretion in any way. See 
    592 F.3d 400
    , 411 (3d Cir.
    2010). The court reasoned that “a probation officer may not decide the nature or extent of
    the punishment imposed upon a probationer.” 
    Id.
     (cleaned up). That’s not what’s
    happening here, where the treatment provider is deciding only the means of court-ordered
    therapy.
    25
    III.
    For the reasons given, we conclude that Special Condition 6 is consistent with 
    18 U.S.C. § 3583
    (d), comports with due process and the First Amendment, and isn’t an
    improper delegation of the court’s authority. Thus, the judgment of the district court is
    AFFIRMED.
