Contractual “Permission-to-Search” Consent in Cloud Terms of Service Validates Provider Scanning and NCMEC Disclosure Without Extinguishing All Privacy

1. Introduction

United States v. Adam Blocker (7th Cir. May 5, 2026) addresses whether evidence of child sexual abuse material discovered after a cloud-storage provider (Dropbox) detected illegal content, reported it to the National Center for Missing and Exploited Children (NCMEC), and later produced data pursuant to a warrant, must be suppressed under the Fourth Amendment.

Background. Dropbox’s terms of service stated (i) users own “Your Stuff,” (ii) Dropbox may examine stored data to ensure lawful use (e.g., obscenity), and (iii) Dropbox may disclose information to third parties when reasonably necessary for specified purposes, including complying with law and preventing abuse. In 2018, Dropbox reported to NCMEC that it found child pornography in files Adam Blocker was sharing. NCMEC alerted federal authorities. The FBI obtained a warrant for Blocker’s devices and Dropbox data, locating additional unlawful images beyond those first sent to NCMEC. Blocker pleaded guilty under 18 U.S.C. §2252A(a) but reserved the right to appeal the denial of his suppression motion.

Key issues. (1) Whether Dropbox’s detection/reporting should be treated as governmental action subject to the Fourth Amendment, given NCMEC’s statutory role and Dropbox’s cooperation with it; and (2) whether Blocker’s acceptance of Dropbox’s terms of service constituted valid consent to Dropbox’s scanning and disclosure such that no warrant or probable cause was required for Dropbox’s actions.

2. Summary of the Opinion

The Seventh Circuit (Easterbrook, J.) affirmed. Without deciding whether NCMEC is a governmental actor, the court assumed for argument’s sake that it is (as in United States v. Bebris) but held suppression unwarranted because Blocker consented—via Dropbox’s terms of service—to Dropbox reviewing stored files and disclosing content for specified purposes. The court rejected the view that consent is ineffective unless the contract says the provider will search and disclose (rather than may), and rejected the framing that consent must “extinguish all expectation of privacy.” Relying heavily on United States v. Adkinson, the court held that an optional grant of permission to inspect/disclose is still consent; action within that scope does not require probable cause or a warrant. The court declined to revisit Adkinson, acknowledged an inter-circuit conflict (with United States v. Lowers, United States v. Maher, and United States v. Warshak), and noted that Supreme Court review in Chatrie v. United States (argued Apr. 27, 2026) could bear on consent questions.

3. Analysis

3.1. Precedents Cited

(a) The Fourth Amendment’s state-action limitation and private-search doctrine

  • United States v. Jacobsen, 466 U.S. 109, 113 (1984): The cornerstone proposition that the Fourth Amendment regulates searches and seizures by public officials, not purely private actors. The opinion emphasizes Jacobsen’s practical relevance by noting Jacobsen itself involved a private search by Federal Express. Jacobsen supports the baseline skepticism toward treating Dropbox as a state actor merely because it reports crime.
  • United States v. Koenig, 856 F.2d 843, 846-50 (7th Cir. 1988); United States v. Young, 153 F.3d 1079 (9th Cir. 1998); United States v. Smith, 383 F.3d 700, 705-06 (8th Cir. 2004); United States v. Gonzalez, 781 F.3d 422, 427-28 (8th Cir. 2015): These cases reinforce the principle that private-carrier inspections and subsequent reporting to law enforcement generally remain private activity, even when done regularly and in cooperation with authorities. The court uses them by analogy: if FedEx searches are private, Dropbox searches are not obviously different.

(b) NCMEC’s status and attribution to government

  • United States v. Ackerman, 831 F.3d 1292, 1296-1300 (10th Cir. 2016) (Gorsuch, J.): Cited for the proposition (accepted by at least one circuit) that NCMEC’s congressionally chartered, publicly funded, statutorily designated clearinghouse role can make it part of the government for Fourth Amendment purposes.
  • United States v. Meals, 21 F.4th 903, 908 (5th Cir. 2021): Cited as the contrary view on whether NCMEC is governmental.
  • United States v. Bebris, 4 F.4th 551, 558 (7th Cir. 2021): The Seventh Circuit previously assumed Ackerman’s approach without deciding; it does so again here. Bebris also matters because it upheld a finding that Facebook’s search of content on its servers was private activity, supporting the prosecution’s “private motive” theory.
  • United States v. Hudson, 86 F.4th 806 (7th Cir. 2023): Cited for the general state-action attribution framework (i.e., when conduct is “fairly attributable” to the United States). Blocker invoked Hudson to argue Dropbox acted as a governmental agent due to its reporting promise and NCMEC-provided detection software.

(c) Consent as an exception to warrant/probable cause

  • Schneckloth v. Bustamonte, 412 U.S. 218 (1973): Establishes that voluntary consent removes the need for probable cause or a warrant, even for police searches. The Seventh Circuit uses Schneckloth to justify focusing on consent as a complete answer once found voluntary and within scope.

(d) Circuit split over terms-of-service consent (may vs will; “extinguish” framing)

  • United States v. Lowers, 170 F.4th 134, 145-48 (4th Cir. 2026); United States v. Maher, 120 F.4th 297, 307-09 (2d Cir. 2024); United States v. Warshak, 631 F.3d 266, 286-87 (6th Cir. 2010): Cited as adopting (in the Seventh Circuit’s characterization) a more demanding approach to contractual consent, treating terms that say a provider may examine/disclose as insufficient, especially where government interests are implicated, and sometimes asking whether consent “extinguishes all expectation of privacy.” The Seventh Circuit expressly rejects that approach as inconsistent with ordinary consent doctrine.

(e) Seventh Circuit’s own controlling consent-in-contract line

  • United States v. Adkinson, 916 F.3d 605 (7th Cir. 2019): The central precedent. Adkinson held that a defendant can consent in advance to collection and sharing of data as a condition of receiving contracted services; the defendant’s Fourth Amendment rights were not violated where T-Mobile’s policy permitted disclosure when reasonably necessary to protect rights/safety. Blocker treats Adkinson as the key obstacle, and the Seventh Circuit treats it as controlling.
  • Medlock v. Trustees of Indiana Univ., 738 F.3d 867, 872 (7th Cir. 2013): Cited in Adkinson (and quoted here) for the proposition that advance consent to searches can be a condition of receiving contracted services.
  • United States v. Young, 350 F.3d 1302, 1308-09 (11th Cir. 2003): Supports enforcing consent to search in a FedEx bill of lading, reinforcing the Seventh Circuit’s view that broadly worded commercial-consent provisions can validate private inspections and related cooperation with law enforcement.

(f) Other authorities

  • Restatement of Consumer Contracts §6 comment 1 (2024): Used to underscore the key contractual safeguard: unconscionable clauses are not enforced. The court notes Blocker did not argue unconscionability.
  • Omri Ben-Shahar & Carl E. Schneider, More Than You Wanted to Know: The Failure of Mandated Disclosure (2014): Acknowledges real-world limits of consumer comprehension, but the court refuses to “read with a thumb on the scale” against clear text.
  • Orin S. Kerr, Terms of Service and Fourth Amendment Rights, 172 U. Pa. L. Rev. 287, 291-304 (2024): Cited as collecting cases; supports the broader doctrinal framing that terms of service can shape Fourth Amendment analysis.
  • Chatrie v. United States, No. 25-112 (argued Apr. 27, 2026): Identified as a potentially forthcoming Supreme Court decision that may influence how consent interacts with compelled or voluntary disclosure, in a context involving Google location data and a geofence warrant.

3.2. Legal Reasoning

(1) The court sidesteps (without resolving) the hardest state-action questions

Blocker’s principal Fourth Amendment theory sought to treat Dropbox’s conduct as government conduct, largely because of (i) NCMEC’s statutory role under 18 U.S.C. §2258A, (ii) NCMEC’s funding/charter, and (iii) Dropbox’s arrangement to report detections and receive detection assistance. The panel acknowledged that attribution is “far from clear” merely because a company routinely informs authorities (analogizing to FedEx and the DEA), and it noted that 18 U.S.C. §2258A(f) explicitly says federal law does not require providers to monitor user content to generate the knowledge that triggers reporting duties—leaving the choice to search “in private hands.”

Even so, the court did not decide whether Dropbox was a governmental agent. Instead, it assumed (as in United States v. Bebris) that United States v. Ackerman is correct about NCMEC (without deciding), and then affirmed on a narrower ground: consent.

(2) Contractual consent is treated as real consent, not “mere fine print” to be discounted

The district court denied suppression because Blocker consented through Dropbox’s terms of service, which “unambiguously permits Dropbox to scan all files at its option and reveal the contents for five specified purposes.” The Seventh Circuit accepted that analysis and rejected the argument that lengthy consumer terms should be judicially re-read against the drafter merely because many users do not study them.

The court emphasized the proper doctrinal “escape valve” for abusive consumer terms: unconscionability. But because Blocker did not argue it was unconscionable for Dropbox to detect and report child pornography, the court treated the contract as enforceable and the consent as operative.

(3) “May” is enough: optional permission is still permission

The panel’s key doctrinal move is its rejection of the may/will distinction relied upon (in its telling) by United States v. Lowers, United States v. Maher, and United States v. Warshak. The Seventh Circuit held that language granting an option to search and disclose is still a “clear grant of permission to inspect.” It offered a straightforward analogy: “You may search my house” authorizes a search; it does not become ineffective because the searching party never promised it would search.

The opinion also notes a practical reason providers may avoid “we inspect all files every day” language: it may be untrue. Consent doctrine, as the Seventh Circuit frames it, turns on authorization within scope—not on frequency, universality, or guaranteed monitoring.

(4) Consent does not require “extinguishing all expectation of privacy”

The Seventh Circuit criticizes the formulation (again, attributed to other circuits’ approaches) asking whether contractual consent “extinguishes all expectation of privacy.” In the court’s view, that framing sets an unrealistically high bar that would rarely be met outside extreme disclosure regimes, and it misconceives how consent functions.

The court’s alternative is more orthodox: consent is a targeted permission given to a particular recipient to do particular acts. A driver can consent to one officer opening the trunk without surrendering all privacy against everyone else (neighbors, family, or other agencies later). Similarly, Blocker authorized Dropbox—“but not Google or T-Mobile”—to inspect and disclose within contractually described purposes.

(5) Adkinson controls, and the Seventh Circuit entrenches the “advance consent by consumer contract” principle

United States v. Adkinson is treated as materially indistinguishable: both T-Mobile and Dropbox reserved an option to collect/review and disclose information under specified conditions. The court characterizes Adkinson as reflecting ordinary contract law where the terms are not unconscionable, and it holds that Adkinson is “incompatible” with the approaches in Lowers, Maher, and Warshak.

The panel declines to reconsider Adkinson, noting that circuit conflict would remain regardless and pointing to Chatrie v. United States as a possible vehicle for Supreme Court clarification on consent’s role in modern digital investigations.

3.3. Impact

(1) Strengthened enforceability of cloud-platform scanning/disclosure terms as Fourth Amendment consent

The decision cements (at least within the Seventh Circuit) a rule that broadly worded terms of service authorizing scanning and limited disclosure can constitute valid consent even when the provider is not obligated to scan and even when disclosure predictably assists law enforcement (including via NCMEC). For suppression motions, this places substantial weight on contract text and scope.

(2) Doctrinal pressure against the “extinguish all privacy” test

By expressly rejecting the “extinguishes all expectation of privacy” framing, the opinion may influence future Seventh Circuit panels—and district courts—toward a more granular “scope of permission” analysis. Litigants challenging provider scans/disclosures will likely be pushed to argue (i) the clause is ambiguous as to the particular conduct, (ii) the conduct exceeded the scope, (iii) consent was not voluntary in a legally meaningful sense, or (iv) unconscionability.

(3) Ongoing circuit split and increased likelihood of Supreme Court resolution

The panel openly acknowledges conflict with United States v. Lowers, United States v. Maher, and United States v. Warshak, and places the dispute in the orbit of Chatrie v. United States. Even if Chatrie focuses primarily on geofence warrants, Blocker flags consent as a recurring and potentially decisive issue in digital evidence cases.

(4) Practical consequences for user privacy and compliance design

Providers operating in the Seventh Circuit may view Blocker as judicial validation for drafting “permission-based” monitoring and disclosure clauses, coupled with discretionary scanning programs, without needing to represent comprehensive monitoring. Defendants, meanwhile, may increasingly litigate unconscionability, contract formation, notice, or scope—rather than relying solely on Fourth Amendment state-action theories.

4. Complex Concepts Simplified

  • State action (government vs. private conduct). The Fourth Amendment restricts the government, not private companies. A private company can sometimes be treated like the government if it is effectively acting as the government’s agent (conduct “fairly attributable” to the United States).
  • Private search doctrine. If a private party conducts a search on its own, the Fourth Amendment generally does not apply to that private party’s actions. (What the government may do afterward can raise additional issues, but Blocker was decided on consent.)
  • Consent search. If a person voluntarily authorizes a search, law enforcement (and, a fortiori, a private party) need not have probable cause or a warrant to conduct the search within the permission granted. Consent can be given in advance and can be limited in scope.
  • “May” vs. “will” in consent language. This case holds that permission stated as an option (“we may examine/disclose”) can still be valid consent. The recipient does not need to promise that it will search; it only needs authorization to do so.
  • Unconscionability. A contract term may be unenforceable if it is so unfair as to be unconscionable. The court treats this as the main contract-law safeguard, but Blocker did not claim Dropbox’s scanning/reporting permissions were unconscionable.

5. Conclusion

United States v. Adam Blocker solidifies a Seventh Circuit rule: when a cloud service’s terms of service clearly grant the provider permission to inspect user files and disclose information for specified purposes, a user’s assent can constitute valid advance consent, and the provider’s actions within that scope do not require probable cause or a warrant—even if the terms say the provider may (not will) inspect/disclose and even if the disclosures assist NCMEC and law enforcement.

The opinion’s most significant contribution is doctrinal clarity on consent: it is a scoped authorization, not a total surrender of privacy. By reaffirming United States v. Adkinson and rejecting the approaches reflected in United States v. Lowers, United States v. Maher, and United States v. Warshak, the Seventh Circuit deepens an acknowledged circuit split—one the Supreme Court may eventually resolve, potentially in the wake of Chatrie v. United States.
