7,095 TikTok Videos Show Teen Ad Rules Can Miss Influencer Posts

A 2026 TikTok audit located the weaker point in teen ad safety beyond the platform's formal ad product: the commercial content around it. Researchers from the Kempelen Institute and Comenius University collected 7,095 TikTok videos over 10 days, classified 1,346 of them as some form of advertising, and found that disclosed and undisclosed commercial posts showed profiling effects toward minor accounts that were 5-8 times stronger than the profiling effects adult accounts saw in formal ads.

That distinction matters because regulators are moving fast on youth safety. Reuters reported on June 18 that Meta had lobbied Congress for legal immunity from child-harm claims as part of Kids Online Safety Act negotiations. Florida sued TikTok on June 15 over its minor-access law. The European Commission has already published DSA guidelines on protections for minors. The audit's claim is narrower than that policy pile-up, but it gives the whole debate a concrete commercial mechanism: a platform can restrict profiled formal ads and still deliver personalized sponsored-looking content through the recommendation feed.

The law sees the ad buy first

The DSA's Article 28(2) prohibits online platforms from presenting advertisements based on profiling when they know with reasonable certainty that the recipient is a minor. The audit argues that the protection is constrained by Article 3(r), which defines an advertisement around information promoted on the platform's interface against remuneration specifically for promoting that information. In practice, that puts the formal platform ad buy in the center of the rule.

The researchers found that formal ads shown to the simulated minor accounts were limited and did not show evidence of profiling toward those minors. That is the compliance story. The exposure story sits elsewhere. The paper says disclosed paid partnerships and undisclosed brand or creator promotional posts were recommended to minor accounts in ways that tracked their simulated interests, with the strongest effect in undisclosed commercial content.

The feed sees the commercial signal

Creator marketing does not always travel through an ad server. A makeup tutorial, gaming clip, supplement routine, snack review, shopping haul, affiliate post, or brand-owned account can function as promotion even when it is not purchased as a formal ad unit. The audit's point is that these posts can be sorted and personalized by the same recommender logic that decides what a teen sees next.

The paper also separates disclosure from delivery. TikTok can give creators a paid-partnership or promotional-content tool, and EU law can require platforms to make commercial declarations possible. If creators do not use the label, or use the wrong label, the commercial content may still move through the feed. The audit says undisclosed commercial posts made up the majority of advertising in its sample and carried the strongest profiling signal.

The U.S. debate is aimed at a different layer

KOSA, as described by Senator Richard Blumenthal's office, focuses on safeguards, default privacy settings, opt-outs from personalized recommendations, parental tools, audits, and a duty to prevent and mitigate specific harms, including ads for certain illegal products. Reuters reported that Meta proposed immunity language while the bill was under consideration, and that lawmakers had not indicated they would adopt it. That fight is about liability, product design, and preemption as much as advertising.

Florida's HB3 is also pointed at access and addictive design. The enacted law requires covered social media platforms to prevent minors younger than 14 from becoming account holders and to obtain parental consent for 14- and 15-year-olds. The June 15 complaint against TikTok alleges violations of that law and deceptive safety representations. It does not answer the audit's narrower question: once a minor is in the feed, which commercial posts count as ads for profiling restrictions?

Disclosure is necessary and incomplete

The U.S. already has a creator-ad rulebook for disclosure. FTC guidance tells influencers to make material connections to brands clear, hard to miss, and attached to the endorsement message. The eCFR version of the Endorsement Guides says advertisers can be liable for misleading endorsements and for failing to disclose unexpected material connections, and it treats social tags, demonstrations, likeness, and other promotional messages as possible endorsements.

That helps a viewer understand who paid. It does not by itself decide whether a platform may profile a teen into more of the same commercial content. For brands, the practical gap is between ad-law compliance and youth-safety scrutiny. A clean #ad label may satisfy one review while the platform's recommender, the product category, and the audience age profile create a second risk.

The brand control has to move upstream

A teen-safety review cannot stop at the media plan. The campaign file should classify every post by commercial purpose before it sorts the post by ad-buy status. Paid partnerships, gifted-product posts, affiliate links, creator whitelisting, brand-account posts, platform shop integrations, and clipping programs all need the same basic fields: who paid, what claim was made, where the disclosure appeared, whether minors can receive the post, and what platform settings control delivery.

The study does not establish a formal-ad DSA violation by TikTok. It identifies a category of commercial content that the formal ad rule may not reach. Evidence for the same pattern across Instagram, YouTube, Snapchat, Roblox, Twitch, or every shopping surface would require separate testing. The practical control question for any teen-visible creator campaign is simple: if the post looks organic but serves a commercial purpose, how is it classified, disclosed, targeted, and logged?

The useful lesson for creator marketing is mechanical. The ad system is now only one way a commercial message reaches a teen. The other way is a creator-style post that looks like feed content, carries a brand incentive, and can still be personalized by interest. Regulators may keep writing rules around ads, age gates, and product features. Brands need a campaign record that follows the commercial signal wherever the feed sends it.
