Crypto Casino Affiliate Disclosure Rules

Affiliate disclosure rules tightened sharply in 2024-2025 and most casino affiliates are still not compliant

The casino affiliate industry — review sites, comparison platforms, streamers, content creators — operates on the basis of commissions paid by operators for player referrals. Disclosure of this financial relationship is required by consumer protection law in most major markets, but enforcement has historically been patchy. That has changed across 2024 and 2025, with the FTC, UK ASA, German consumer protection authorities and EU Digital Services Act enforcement all targeting gambling-related affiliate content for inadequate disclosure. This guide explains the actual legal requirements by jurisdiction, what compliant disclosure looks like in practice, and the specific patterns of non-compliance that have triggered regulatory action.

The FTC framework in the United States

The US Federal Trade Commission's endorsement guidelines (16 CFR Part 255), updated most recently in 2023, require any commercial endorsement of a product or service to disclose material connections between the endorser and the operator. Material connections include any compensation — flat fees, revenue share, free products, comped travel — that a reasonable consumer would want to know about when evaluating the endorsement. For casino affiliates this means disclosing that the affiliate earns commission on referred deposits or losses, in clear and conspicuous language.

The FTC's 2023 guidance specifies that "clear and conspicuous" means the disclosure must be near the endorsement, in language consumers will understand, and not buried in fine print or behind a hyperlink. For a casino review article, this means the disclosure should appear in the first viewport of the page, not at the bottom in a "small print" section. For a video review, the disclosure must be both verbally stated and on-screen for sufficient duration. For a social media post, the #ad or #sponsored hashtag must appear prominently, not hidden in a long string of tags.

FTC enforcement against gambling-related disclosure failures accelerated in 2024-2025. The agency issued multiple compliance demand letters to affiliate publishers and brought formal action against several creators in the sports betting space who routinely promoted operators without disclosure. Penalties have ranged from compliance orders to financial settlements, with the largest single 2025 settlement reaching $1.4 million against a specific creator network.

The UK Advertising Standards Authority

The UK Advertising Standards Authority (ASA) enforces the CAP Code, which requires gambling marketing to be "obviously identifiable" as such, not to target under-18s, and not to be misleading. Affiliate disclosure under UK rules requires the word "ad," "advertisement," "sponsored" or equivalent to be clearly visible at the start of any sponsored content. The ASA's gambling-specific guidance prohibits content that suggests gambling can solve financial problems, that depicts behaviour likely to cause harm, or that uses imagery designed to appeal to minors.

The ASA has been particularly active against UK-facing gambling affiliates since 2023. The "Gambling Advertising — Children, Young Persons and Vulnerable Persons" review by the ASA in 2023 produced rule updates that significantly restricted what gambling affiliates can publish. UK-licensed gambling operators have direct compliance obligations under UKGC license conditions to ensure their affiliates follow the rules; operators have lost licenses partly due to affiliate misconduct in the past.

EU jurisdictions and the DSA

The EU Digital Services Act, fully in force since February 2024, imposes additional disclosure obligations on online platforms hosting commercial content. Large platforms (VLOPs) must implement systems for advertisers to mark content as commercial, and creators on these platforms must use the platform's disclosure tools. The DSA enforcement against gambling content has been limited so far, with most action focused on adult content and disinformation, but the framework applies.

Member-state specific rules add additional layers. Germany's Glücksspielstaatsvertrag (GlüStV) requires affiliates promoting any gambling operator to ensure the operator holds a German license, with affiliates liable for promoting unlicensed operators to German users. The German consumer protection authority has issued multiple cease-and-desist notices to affiliates targeting German traffic without ensuring license compliance. The Netherlands and France have similar restrictions through their respective gambling authorities.

The practical effect is that EU-facing affiliates must verify the operators they promote hold appropriate licenses for each user's residence, which is operationally complex and limits which operators can be advertised to which audiences.

What compliant disclosure actually looks like

A compliant disclosure on a casino review site typically includes a statement at the top of the article — visible in the first viewport — that reads something like: "This review contains affiliate links. We earn commission if you sign up through these links, but this does not affect our ratings or recommendations." The phrasing should be plain language, not legal jargon, and not obscured by formatting.

For video content, the disclosure should be both stated at the start of the video and visible as on-screen text for at least the first 15 seconds, with repeated mentions during the video for content longer than 60 seconds. For live streams, the disclosure should be in the stream description, in the stream chat as a pinned message, and verbally stated periodically by the streamer.

For social media posts, the #ad or #sponsored tag should appear at the start of the post text, not after several other tags or hidden behind a "see more" expansion. Image-based platforms (Instagram, TikTok) typically require both the platform's branded content tool and a separate disclosure in the caption.

The compliance gap

Despite the regulatory clarity, compliance remains inconsistent. A 2024 audit by the UK ASA of gambling-related social media content found 47% of reviewed posts had inadequate disclosure. A 2024 University of Bristol study of US-facing gambling affiliate sites found 34% had no disclosure at all and another 22% had disclosures that did not meet FTC clarity standards. The gap is driven by a combination of affiliate-side ignorance (many smaller creators are not aware of the requirements), enforcement asymmetry (regulators target the largest violators, leaving smaller violations unpenalized), and the structural conflict of interest in disclosing financial arrangements that may reduce reader trust.

For affiliates operating professionally, full compliance is the prudent path both legally and reputationally. Disclosure has a small effect on conversion rates (typically 5-10% reduction per industry studies) which is well outweighed by the legal exposure of non-compliance for any operation at scale.

FAQ

Do I need to disclose if I am not paid in cash? Yes. Material connections include any compensation, including comped accounts, free play, products, travel or other non-cash value.

Is disclosure required for organic search content? Yes. Whether the user arrives via search, social media, or direct link, the disclosure requirement applies to the content itself.

What if I disclose my affiliation in an "About" page but not on each article? Most regulators require disclosure near the endorsement, not on a separate page. The "About page only" approach is generally not sufficient.

Are review aggregators (TripAdvisor-style) subject to the same rules? Yes, if they receive operator-side payments for placement or commission on referrals. The form of the site does not exempt it from disclosure requirements.

What is the penalty range for affiliate disclosure violations? FTC penalties typically range from compliance orders for first offenses to financial penalties of $5,000-$1,000,000+ for repeat or egregious violations. UK ASA actions typically involve ad bans and reputational publication rather than financial penalties for affiliates specifically.
