How to block a YouTube channel from recommendations?

To block a YouTube channel from recommendations, you can utilize YouTube’s built-in features and third-party browser extensions:

• “Don’t recommend channel” feature: When a video from an unwanted channel appears in your feed, click the three vertical dots next to the video title or thumbnail and select “Don’t recommend channel”. This action is intended to prevent future recommendations from that specific channel, though users report its effectiveness can be inconsistent.
• “Block user” or “Hide user from my channel”: On a channel’s page, locate the “Block user” or “Hide user from my channel” option, often found under the “About” tab, via a flag icon, or the three-dot menu. This option prevents the channel’s content from appearing in your feed and blocks the user from commenting on your videos. This block applies across devices when signed into your YouTube account.
• Browser Extensions: For a more robust solution that can block channels from appearing even in search results, consider using browser extensions like BlockTube. These extensions allow you to block specific channels by name or ID within the browser where they are installed.
• Clear History: Regularly clearing your YouTube search and watch history, along with “Not interested” feedback, can also help manage recommendations. Be aware that clearing “Not interested” feedback will unblock all channels you previously marked as such.
