TikTok For You Feed Rabbit Hole: EU Says the Feed Breaches the Digital Services Act

The TikTok For You feed rabbit hole is now a formal regulatory charge in Europe, not just a complaint users make about their own scrolling. On 6 November 2026, the European Commission preliminarily found TikTok in breach of the Digital Services Act (DSA) over the way its recommender system keeps serving similar videos, saying the platform had neither assessed the risk properly nor reduced it with measures that work (European Commission). Information verified through 9 November 2026.

Preliminary matters. TikTok can examine the investigation file and reply in writing, and no fine has been imposed. But if the Commission confirms its view, it can issue a non-compliance decision carrying a fine of up to 6% of the provider’s total worldwide annual turnover (Securities.io).

The TikTok For You feed rabbit hole, as Brussels describes it

The Commission’s description is plain. TikTok’s For You feed “shows users a continuous stream of personalised videos, even when those are related to mental health struggles and body image,” and “the more a user interacts with a certain type of content, the more TikTok’s ‘For You’ feed algorithm recommends similar content” (European Commission).

That loop turns harmful, the Commission says, when endless, repeated exposure involves content about sadness, isolation or body image. Such rabbit holes “can have a detrimental impact on users’ mental health, especially that of vulnerable adults and minors” (European Commission). The possible effects listed in the detailed reporting include increased sadness or anxiety, body dissatisfaction, lower self-esteem, and a worsening of existing eating disorders and mental conditions (PPC Land).

Note who is covered. This case is not confined to children. Vulnerable adults are named alongside minors, which widens it beyond the child-safety framing that has driven most feed legislation of the past two years (PPC Land).

The TikTok viewing time recommendation signal is the point

Two legal duties sit underneath the finding. Article 34 of the DSA requires very large platforms to assess systemic risks from their systems; Article 35 requires them to mitigate those risks. On the first, the Commission preliminarily found TikTok “did not adequately assess how its recommendation algorithm may lead users into such ‘rabbit holes’, putting their wellbeing at risk” (PPC Land).

On the second, TikTok had not done nothing — it had put measures in place. The Commission’s objection is that they do not work. Its diversification measures “do not sufficiently reduce how often similar content is recommended,” its control tools “do not effectively enable users to control the content recommended to them,” and tapping “not interested” “may not be enough to change the content feed” (PPC Land; Engadget).

The sharpest line in the findings concerns what the system listens to. According to the Commission, “the algorithm prioritises showing users content based on viewing time, over their choice to see less of certain content” (PPC Land). Watch a triggering video for a few seconds too long — out of shock, confusion, anything — and the system reads attention as approval.

So Brussels wants design changes, listed as examples at this stage: rely more on users’ explicit preferences, disable viewing time as an indicator to recommend content, make controls more accessible and usable, and regularly test the algorithm (European Commission; Securities.io). No deadline, technical standard or measurement method was published with the findings (PPC Land).

A Digital Services Act recommender system risk case, not another design case

This strand is one piece of a much longer file. The Commission opened formal proceedings against TikTok on 19 February 2024, and the rabbit-hole question was in scope from the start (PPC Land). In February 2026 it preliminarily found TikTok’s addictive design in breach, citing infinite scroll, autoplay and push notifications; in July 2026 a further set of findings addressed the protection of minors’ accounts (Engadget).

February and November are not the same complaint twice. February was about compulsive use — features that keep people scrolling longer than they intend. November is about content concentration: what the algorithm keeps showing, however long the session lasts. A user could respect every screen-time break and still spend each session inside the same narrow loop (PPC Land).

The evidence behind the preliminary view, per the Commission, includes TikTok’s own risk-assessment reports, internal data and documents, answers to multiple information requests, a review of scientific research, and interviews with experts in recommender systems, psychology and psychiatry, with support from Ireland’s Digital Services Coordinator, Coimisiún na Meán (Securities.io). None of the underlying figures — how often similar content recurs, how many users are affected — were made public with the announcement (PPC Land).

TikTok disputes the case outright. “The Commission has made a series of statements that are fundamentally inaccurate and distort our platform’s architecture and our commitment to user safety,” the company said, adding: “We have a strong record of protecting our community while giving users direct and intuitive control over their content experience” (Engadget).

Executive Vice-President Henna Virkkunen put the Commission’s principle in one sentence: “The Digital Services Act makes platforms responsible for addressing the negative effects related to their recommender system” (Securities.io).

Analysis: the fight that matters is over a single signal. Viewing time is the cheapest, most abundant data a short-video feed produces, and it built the For You page’s reputation for eerie accuracy. Brussels is arguing that the signal is also unreliable in exactly the cases where harm concentrates — that lingering is not liking. If that argument survives TikTok’s reply, every engagement-ranked feed operating in Europe, not just TikTok’s, will have to show what its stated-preference controls actually do against its behavioural ones. That is a design question with a legal deadline attached, and it is why a preliminary finding about one feed reads like a ruling about all of them.
