EU Preliminarily Finds TikTok's For You Feed Breached Digital Services Act

The European Commission announced on November 6 that it had preliminarily found TikTok in breach of the Digital Services Act because its engagement-based For You recommender can lead users into harmful rabbit holes. The findings target the design of the feed, not an individual video. According to the Commission, the system shows users a continuous stream of personalised videos, even when those videos relate to mental health struggles and body image. TikTok has 189 million users in the European Union, and the case could eventually bring a fine of up to 6 percent of the provider's total worldwide annual turnover.

The case is being pursued under the Digital Services Act, which the Commission says makes platforms responsible for addressing the negative effects of their recommender systems. Officials examined lawful content rather than a single illegal post. They said one video on a sensitive theme might not be problematic, but the cumulative effect of watching scores of similar videos could damage mental health. The alleged harm therefore comes from repetition and amplification, not from the presence of prohibited material. That distinction is central to the investigation.

The inquiry has been building for more than two years. Reuters reported on November 6 that the charges are part of a broader DSA investigation opened in February 2024. The Commission had already charged TikTok in February 2026 over addictive design, inadequate child protection and restrictions on researcher data access, and it issued separate findings on minors in July 2026. POLITICO reported on November 6 that the latest action is the fifth case in which the EU executive has accused TikTok of breaching EU rules, although no fines have been issued against the Chinese-owned platform so far.

TikTok disputes the characterisation. The Guardian reported on November 6 that the company called the statements fundamentally inaccurate and said they distorted its architecture and safety commitment. TikTok says its policies prohibit content that promotes disordered eating. The company also points to the use of its controls, saying that more than 79 million EU users used its not interested option or keyword filters in the first half of 2026. The dispute now turns on whether those tools are meaningful safeguards or cosmetic fixes layered on top of a recommender that still rewards engagement.

Key Facts

The Commission's preliminary findings cover two obligations under the DSA: risk assessment and risk mitigation. The Commission found that TikTok did not adequately assess how its recommendation algorithm may lead users into rabbit holes. It also found that the company failed to implement proportionate, reasonable and effective measures to address the risk. Existing safeguards, including the not interested button and the option to refresh the feed, were judged ineffective. The Commission said that at this stage TikTok needs to change the design of its For You feed.

Henna Virkkunen, the Commission's executive vice president for tech policy, framed the issue as a direct consequence of engagement optimisation. 'Every time a user scrolls or likes a video on TikTok, the algorithm serves more of the same, leading users down rabbit holes they cannot easily escape from,' she said. The remedy is not limited to removing individual videos. Reuters reported on November 6 that regulators want TikTok to rely more on users' explicit preferences, make user controls easier to access and use, and regularly test its algorithm.

The procedural stakes are substantial. TikTok can examine the investigation file and reply in writing. If the preliminary findings are confirmed, the Commission may issue a non-compliance decision carrying a fine of up to 6 percent of the provider's total worldwide annual turnover. Reuters reported that ByteDance, TikTok's Chinese owner, risks a fine next year unless it resolves the issue. The Commission has not imposed a penalty in its earlier TikTok cases, so the immediate pressure is on product design and documented remedies rather than on an immediate payment.

POLITICO reported on November 6 that the case marks the first time the Commission has focused on a social media platform's recommender system as a breach of the DSA. A Commission official, speaking on condition of anonymity, said: 'This is the first time that we are really tackling head-on the engagement-based recommender system model.' Officials also said TikTok should give more weight to explicit signals, such as the not interested button, than to implicit engagement signals, such as watch time. The DSA offers a non-personalised feed as an alternative, but only 0.2 percent of TikTok users select that option, according to an official cited by POLITICO.

Analysis

The bigger picture here is that regulators are moving from policing individual posts to policing the architecture that decides what becomes visible. This case is different from a conventional takedown dispute because the videos at issue are lawful. The alleged harm arises from the way the system learns from engagement and then supplies more of the same, especially when the subject matter is sadness, isolation or body image. If the Commission's approach survives challenge, the recommender itself becomes a regulated product feature rather than a neutral delivery mechanism. That would be a significant shift in how the DSA is applied.

That shift explains why the not interested button matters so much. Officials are not asking TikTok to abolish personalisation. They are asking it to rebalance the signals that drive personalisation. Under the current design, a scroll, a like or watch time can function as an implicit vote for more content like the last video. Explicit signals are supposed to give users direct control. The Commission's finding that the button was ineffective suggests that the system either does not weight the signal heavily enough or quickly reverts to its previous pattern. Easier controls and regular algorithm testing are meant to make that signal stick.

The 0.2 percent figure for the non-personalised feed cuts both ways. It shows that almost nobody chooses to abandon personalisation, which weakens the argument that a simple opt-out is a sufficient safeguard. It also shows how central the personalised feed is to TikTok's user experience. The Guardian described the case as one that strikes at the company's business model, and that commercial context helps explain why the dispute is more consequential than a single content takedown. TikTok's claim that the findings are fundamentally inaccurate signals that it will contest the technical characterisation, but it must still offer remedies that satisfy the regulator.

Why It Matters

The case affects a very large audience. TikTok has 189 million users in the EU, and the Commission's findings are specifically concerned with young and vulnerable users. The Guardian reported on November 6 that the investigation found repetitive content could lead to anxiety and sadness or worsen existing eating disorders and mental health problems. Because the platform is used by minors, the outcome will shape how far Brussels can go in requiring safety features that change what users see, not merely what they are told about the content.

It also creates a template for other platforms. The Commission is separately investigating rabbit hole effects on Meta's Facebook and Instagram, according to Reuters. If the TikTok case produces accepted remedies, those measures could become a reference point for how engagement-based recommenders are assessed across the industry. If TikTok fights the findings and wins, the Commission's effort to treat recommender design as a systemic risk may be harder to extend. Either way, the case tests whether the DSA can regulate the cumulative effects of lawful content, not just the presence of illegal material. A fine of up to 6 percent of worldwide annual turnover gives Brussels leverage, but the Commission has issued no fines against TikTok so far and has previously closed a DSA advertising-transparency case after the company agreed to fixes.

Next Up

TikTok now has the opportunity to examine the investigation file and respond in writing. The company can defend its practices and propose remedies that the Commission considers acceptable. The Commission will then decide whether to confirm the preliminary findings and issue a non-compliance decision. Reuters reported that ByteDance risks a fine next year unless the issue is resolved, so the next phase will centre on whether TikTok changes the For You design, gives greater weight to explicit user preferences and submits its algorithm to regular testing.

The parallel Meta investigation adds to the pressure. Regulators are examining rabbit hole effects on Facebook and Instagram, which means the reasoning in the TikTok case could travel quickly to other recommendation systems. For now, the central question is whether TikTok can show that its controls have a real effect. The Commission's position is that they do not. TikTok's response will determine whether this becomes a negotiated redesign, a prolonged legal fight, or the first recommender-system penalty under the DSA.
