The European Commission issued a preliminary ruling against TikTok, alleging the platform has failed to adequately protect users’ mental health through its recommendation algorithm. The investigation found that the Chinese-owned social media platform, which maintains 189 million users across the EU, exposes users to repetitive content streams on themes including body image and isolation that can contribute to anxiety, depression, and deterioration of existing eating disorders or mental health conditions.
EU regulators determined that while individual videos on problematic themes may not cause harm in isolation, the cumulative effect of viewing numerous similar videos can negatively impact users’ psychological wellbeing. The investigation specifically examined the “rabbit-hole effect,” where users are served narrow and repetitive content designed to maintain engagement. Officials found that TikTok’s existing safeguards against this phenomenon are insufficient. For instance, when users select a “not interested” option on content related to eating patterns, the algorithm continues to recommend similar material on diet and body image. Additionally, refreshing the feed provides only temporary relief from topical content streams.
TikTok disputed the findings, characterizing them as inaccurate and asserting that the platform maintains strong user safety policies and prohibits content promoting disordered eating. The company noted that over 79 million EU users utilized content filtering tools during the first half of 2026. EU officials indicated that the investigation targets TikTok’s business model, which prioritizes user engagement and extended scrolling time. The commission has requested that TikTok redesign its recommendation system to grant users greater control over displayed content.
The preliminary ruling emerges from a broader examination initiated in 2024 under the Digital Services Act, which requires large technology platforms to address various harms including mental health damage. If EU officials ultimately sustain the findings, TikTok faces potential fines of up to 6 percent of global annual turnover. The company has been afforded an opportunity to review investigation materials and present a defense, with the possibility of avoiding penalties through voluntary modifications to its recommender system.
