European Commission preliminarily finds TikTok in breach of the DSA over the 'rabbit hole effect' of its For You recommender system
Nov. 6: the Commission preliminarily found TikTok's For You feed has a harmful 'rabbit hole effect' under the DSA. Not a final decision; no fine yet.
This is a preliminary finding, not a final decision and not a fine. On November 6, 2026 the European Commission said it had preliminarily found that TikTok breaches the Digital Services Act (DSA) over the so-called rabbit hole effect of its For You recommender system. The Commission says the more a user engages with a type of content, the more similar content the algorithm serves, which can be harmful when it involves sadness, isolation or body image.
The essentials
- What was found: TikTok did not adequately assess how its algorithm could lead users into rabbit holes, and its mitigation measures appear ineffective.
- The mechanism: the algorithm uses signals such as watching and liking videos; the Commission says this can harm vulnerable adults and minors.
- What the Commission wants: at this stage it considers TikTok needs to change the design of the For You feed.
- What happens next: TikTok can read the investigation file and reply in writing. A non-compliance decision could come only if the views are confirmed, with a fine of up to 6% of worldwide annual turnover.
How does this fit with earlier findings?
It is part of the same proceedings opened in February 2024. The Commission issued preliminary findings on addictive design in February 2026 (infinite scroll, autoplay, notifications, personalised recommendations) and on protection of minors in July 2026. Those earlier findings do not prejudge the outcome, the Commission said. TikTok's Dublin-based European headquarters falls under Ireland's media regulator, Coimisiún na Meán, which supported the investigation.
What has TikTok said?
We did not find TikTok's response to the November 6 findings. In February, when the addictive-design findings came out, a spokesperson called them categorically false and meritless and said TikTok would challenge them. That statement concerns the earlier findings, not this one.
What is not established
- Whether the findings will be confirmed: TikTok can still respond in writing.
- Whether a fine will be imposed, and how large: none decided; 6% is only the legal ceiling.
- Whether the algorithm actually harms users in the way described: this is the Commission's preliminary view.
- What design changes the Commission would accept: not specified beyond changing the For You feed.

What does 'rabbit hole effect' mean?
The Commission's term for a feed that serves more and more similar content as a user engages with it.
Method and limits
Sources checked on November 6, 2026. We did not read the Commission's November 6 press release itself; we relied on RTÉ and other coverage. TikTok's reply to the November findings was not found. This is not legal advice.
