EU accuses TikTok of breaching digital rules over 'rabbit hole' algorithm

–

Neutral summary

On Friday, November 6, the European Commission announced preliminary findings that TikTok's recommendation algorithm violates the Digital Services Act (DSA) due to a 'rabbit hole effect': the system feeds users increasingly similar videos, potentially worsening depression, loneliness, and body image issues, especially among minors and vulnerable groups. The regulator requires the platform to radically change its personalized feeds, including the 'For You' function, and warns of a possible fine of up to 6% of global annual turnover. This is the first time the Commission has treated a social media platform's recommender systems as a breach of the DSA. The investigation was opened in 2024. Executive Vice President Henna Virkkunen said: 'Every time a user scrolls through a video on TikTok or likes it, the algorithm offers even more similar content, pulling the person into a kind of rabbit hole from which it is hard to escape.' TikTok, owned by China's ByteDance, rejected the findings as 'fundamentally inaccurate'. In the UK, the consumer protection regulator has been urged to investigate TikTok's algorithm following the EU action. Experts note the case could have implications for other platforms using similar recommendation systems.
