What is TikTok´s Rabbit Hole Effect that is banned by the EU?

Social Media News Europe - TikTok´s Rabbit Hole Effect is in breach of the European Commission´s Digital Services Act (DSA), according to an EU announcement on its formal proceedings to investigate TikTok's compliance with the Digital Services Act, dated November 6, 2026. The European Commission´s preliminarily findings state that TikTok does not adequately assess how its recommendation algorithm may lead users into such Rabbit Holes, putting their wellbeing at risk. TikTok now has the possibility to exercise its right to defence. If the European Commission's wins the proceedings against TikTok, the European Commission may issue a non-compliance decision, which can trigger a fine proportionate to the nature, gravity, recurrence and duration of the infringement and the fine can reach up a maximum of 6% of its total worldwide annual turnover.
What is the Rabbit Hole Effect that is banned by the EU?
The Rabbit Hole Effect that is banned by the EU and that is used by TikTok is the recommender system on the user´s feed that shows a continuous stream of personalized videos, even when those are related to mental health struggles and body image. The more a user interacts with a certain type of content, the more TikTok's algorithm recommends similar content in the user´s feed, creating a Rabbit Hole Effect that can be harmful when such endless and repeated exposure involves, for example, content about sadness, isolation or body image. These Rabbit Holes can have a detrimental impact on the mental health of social media users, especially for vulnerable adults and minors.
TikTok´s algorithm plays an important role in the emergence of the Rabbit Hole Effect by using information about user engagement, such as watching and liking videos, to personalize the content recommended to them. For example, when a user repeatedly watches or likes content that may be triggering, such as content about weight-loss or body image, the system interprets these interactions as positive signs of interest and recommends more of the same. Repeated exposure to such content may have serious negative effects on users' wellbeing, including increased feelings of sadness or anxiety, body dissatisfaction, lower self-esteem, or worsening of existing eating disorders and mental conditions.
As part of the European Commission´s proceedings against TikTok´s Rabbit Hole Effect, the preliminary findings denounced its addictive design on February 2026, as well as the risks related to the protection of minors in July 2026.
¨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. The Digital Services Act makes platforms responsible for addressing the negative effects related to their recommender system.¨ - Henna Virkkunen, Executive Vice-President for Tech Sovereignty, Security and Democracy.
