EU preliminarily finds TikTok For You feed breaches DSA over rabbit holes

The European Commission preliminarily found on 6 November 2026 that TikTok's For You recommender breaches the Digital Services Act through a so-called rabbit hole effect, in which the algorithm repeatedly serves similar videos on mental health struggles and body image.

Politico and Euronews reported that the findings mark the first DSA case focused on an engagement-based recommender. If confirmed, fines can reach up to 6% of worldwide annual turnover. TikTok called the statements fundamentally inaccurate and said it has a strong record of protecting users.

What the Commission alleges

According to the Commission's digital-strategy release, TikTok's For You feed shows a continuous stream of personalised videos even when those relate to mental health struggles and body image. The more a user interacts with a type of content, the more similar content the algorithm recommends. That design can be harmful when endless exposure involves sadness, isolation or body image, with a particular risk for vulnerable adults and minors.

The preliminary findings focus on both risk assessment and mitigation. Officials told Politico the evidence was strongest on mental health impacts. The inquiry is the fifth DSA charge track against TikTok, though no DSA fine has yet been issued against the platform. Wire coverage also noted Irish regulator Coimisiún na Meán's support for the probe, consistent with TikTok's European establishment footprint.

What Brussels wants changed

Coverage of the press briefing and Euronews reporting summarised several remediation directions. Regulators want TikTok to give greater weight to explicit user preferences, including not-interested signals, over engagement metrics such as watch time. They also want the company to stop relying on viewing time as a driver of recommendations, make user controls easier to access, and regularly test the algorithm. Officials said current mitigation has not been effective enough. Only about 0.2% of TikTok users select the non-personalised feed option that the DSA also contemplates, according to Politico.

Defence and next steps

A TikTok spokesperson told Euronews and Politico that the Commission had made statements that are "fundamentally inaccurate and distort our platform's architecture and our commitment to user safety," adding that the company gives users "direct and intuitive control" over their content experience.

Preliminary findings are not a final non-compliance decision. TikTok has a right of defence and can propose remedies. The company previously closed a DSA investigation on advertising transparency by agreeing fixes with the Commission. Parallel DSA work on Meta's Facebook and Instagram addictive-design features was noted in Euronews coverage as part of a broader enforcement push on platform design rather than only on individual posts.

Why it matters for European platforms

For European founders and product teams, the case is a concrete signal that recommender design itself - not only content moderation queues - sits inside DSA systemic-risk duties for very large online platforms. Engagement optimisation that traps users in distressing loops is now an explicit Commission enforcement theme. Product managers shipping feed ranking across the EU should treat explicit negative feedback as a first-class signal, document rabbit-hole testing, and expect auditors to ask for evidence that mitigations work in practice.

Europreneurs Media will watch whether TikTok offers a redesign package that regulators accept, or whether the file advances to a confirmed breach and fine.
