The European Commission has charged TikTok with breaching the EU's Digital Services Act over the "rabbit hole" effect of its recommender system, saying the platform failed to mitigate risks to users' mental health from endless exposure to content about sadness, isolation or body image. TikTok's owner ByteDance risks a fine next year of up to 6% of its global annual turnover unless it can resolve the issue.
The charges, announced on Friday, are preliminary findings, and the Commission said TikTok needs to change the design of its 'For You' feed algorithm and should rely more on users' explicit preferences, increase the accessibility and usability of user controls, and regularly test its algorithm.
EU tech chief Henna Virkkunen said in a statement: "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. Today's preliminary findings show again that TikTok needs to step up its efforts to protect users' well-being, including those of minors."
The Commission said endless and repeated exposure to such content can have a detrimental impact on mental health, especially for vulnerable adults and minors.
The charges are under the Digital Services Act, which requires large online platforms to address harmful and illegal content.
This is part of a broader investigation. In February, EU regulators charged TikTok over what they said were addictive designs, inadequate child protection, and making it difficult for researchers to request access to public data. TikTok said at the time those preliminary findings were "categorically false" and it would take steps to challenge them.
The Commission is also separately investigating so-called rabbit hole effects from Meta Platforms' Facebook and Instagram recommendation systems.
Analysis
Why This Matters
- The charges could force TikTok to fundamentally redesign its core recommendation algorithm, affecting how content is served to over 150 million EU users.
- This is one of the most significant enforcement actions under the Digital Services Act, setting a precedent for how regulators tackle algorithmic harm.
- The outcome will test whether EU digital regulation can compel platforms to prioritize user well-being over engagement metrics.
Background
The Digital Services Act (DSA) imposes stricter obligations on very large online platforms to assess and mitigate systemic risks, including risks to mental health. The Commission opened an investigation into TikTok in February 2024, issuing preliminary findings on addictive design and child safety. The latest charges focus specifically on the rabbit hole effect in TikTok's For You feed.
Key Perspectives
European Commission: Says TikTok's algorithm creates harmful rabbit holes by recommending similar content based on user interactions, leading to endless exposure to distressing material, and requires the platform to implement proportionate mitigation measures.
TikTok: Described the February preliminary findings as "categorically false" and said it would challenge them. No response to the latest charges is included in these sources.
What to Watch
- TikTok's formal response and any proposed changes to its algorithm before the Commission's final decision.
- The potential fine of up to 6% of global turnover, which could be billions of euros.
- The separate investigations into Meta's Facebook and Instagram over similar rabbit hole effects.
