Investigation Shows That YouTube’s User Controls are Ineffective

Google-owned YouTube says that people can manage their video recommendations through the feedback tools the platform offers. But do YouTube’s user controls actually work? A new investigative report from Mozilla and co-author Jesse McCrosky, who also writes for, shows that they really don’t.

22,722 volunteers donated their data to the non-profit organisation Mozilla, who’s behind the non-intrusive browser Firefox. The data – including recommendations of more than 560 million YouTube videos – was scrutinized to determine how much control people actually have over the YouTube’s recommendation algorithm.

Here are the top findings:

  • People don’t trust YouTube’s user controls. More than a third (39.3%) of the people surveyed felt YouTube’s user controls did not impact their recommendations at all. Said one participant: “Nothing changed. Sometimes I would report things as misleading and spam and the next day it was back in […] Even when you block certain sources they eventually return.”
  • Data confirms people are right. Mozilla’s analysis of 560 million recommended videos revealed that using the “Do not recommend channel” button prevented only 43% of unwanted recommendations. Other controls had even less of an impact: The “Dislike” and “Not interested” buttons only prevented 12%.

According to the executive summary of the report, there are examples of lost control. One participant asked YouTube to stop recommending firearm videos — but was shortly after recommended more gun content. Another person asked YouTube to stop recommending cryptocurrency get-rich-quick videos, but then was recommended another crypto video.

Some of the recommendations of the report is that YouTube should design its feedback tools in a way that puts people in the driver’s seat, and that YouTube should provide researchers with access to better tools that allow them to assess the signals that impact YouTube’s algorithm.
