The European Commission has formally charged TikTok with breaching the European Union’s Digital Services Act, saying the platform’s powerful recommendation system traps vulnerable users in a harmful cycle of distressing content. In preliminary findings issued on Friday, 6 November 2026, the Commission said TikTok’s For You feed creates what regulators describe as a rabbit hole effect, repeatedly serving users content about sadness, isolation and body image that can damage mental health, including among minors.
The case strikes at the heart of how TikTok works. Unlike a chronological feed, the For You page is driven by an algorithm that learns from every video a person watches, likes or skips, and serves up more of the same. The Commission’s concern is that once a user engages with content about low mood or body image, the system keeps pushing similar material, narrowing what they see and deepening the spiral.
TikTok has around 189 million users across the European Union, making it one of the largest social media platforms operating under the bloc’s rules. The Commission said the company had failed to put in place proportionate, reasonable and effective measures to reduce the risks created by its own recommender system. In the Commission’s view, the platform should have done far more to protect the wellbeing of the people who use it every day.
The preliminary findings set out a series of changes the Commission expects TikTok to make. The company must change the design of its feed so that it relies more on the explicit preferences users themselves state, rather than on inferred signals drawn from their viewing behaviour. It must also improve the controls available to users, giving them clearer and more effective ways to shape what they see, and it must regularly test its algorithm to check whether it is causing harm.
EU tech chief Henna Virkkunen said TikTok needs to step up its efforts to protect users’ wellbeing. Her remarks underline the Commission’s position that a platform of TikTok’s scale cannot treat the mental health effects of its design as a side issue. The findings are preliminary, which means they do not amount to a final finding of a violation, and TikTok will have the opportunity to respond before the Commission reaches a final decision.
If the finding is ultimately upheld, the consequences for TikTok’s parent company ByteDance could be severe. Under the Digital Services Act, the Commission can impose a fine of up to six per cent of a company’s global annual turnover. For a company of ByteDance’s size, that would run into billions of euros, one of the bloc’s most significant enforcement actions against a social media platform.
The investigation itself has been running for some time. The Commission opened the probe in February 2024 under the Digital Services Act, the EU’s landmark law for regulating large online platforms. It has already issued preliminary findings against TikTok twice before, in February 2026 over addictive design and in July 2026 over the protection of minors. The latest findings add a further strand to a case that has steadily widened in scope.
TikTok has strongly disputed the Commission’s conclusions, describing them as a categorically false and entirely meritless depiction of its platform. The company is expected to contest the findings in its formal response. For regulators in Brussels, the case is about whether an algorithm can be treated as a product choice with real consequences for users. For TikTok, it is about defending the feed that made it one of the world’s most popular apps.
