How to Block a YouTube Channel (So It Actually Stays Gone)
Last updated: August 2026
Quick answer: Install the free Dehook extension and click the small ban button that appears on any video in your feed, or type the channel name in the popup’s Blocked channels list. Every video from that channel disappears from your feed, search, and sidebar. YouTube’s own Don’t recommend channel button is temporary and does not touch search; Mozilla’s research measured it only prevents about 43 percent of recommendations.
YouTube’s built-in option sounds right and works wrong. Don’t recommend channel is a suggestion to the algorithm, not a rule: measured effectiveness is around 43 percent, it quietly decays, and search results ignore it completely.
The Dehook approach
Dehook blocks on your side of the screen. If a channel is on your list, its videos are simply never shown: homepage, sidebar, search, everywhere. The block also removes the temptation loop where you keep seeing a channel you dislike and engagement keeps teaching the algorithm you care about it.
Block a channel in 3 steps
- Install Dehook. Add the free extension to your browser.
- Click ban on any video. Hover a video from the channel and click the ban button Dehook adds next to the channel name. Or open the popup and add the channel under Blocked channels.
- Done. All videos from that channel are filtered from your homepage, search results, and recommendations. Unblock any time from the popup list.

FAQ
Why not just use YouTube's Don't recommend channel?
Because it barely works. Mozilla’s RegretsReporter study found it prevents only about 43 percent of recommendations from that channel, it can reset over time, and it never applies to search results. A client-side block simply never renders the channel’s videos.
Is there a limit on how many channels I can block?
No practical limit. Some popular blockers cap out around 400 channels; Dehook’s list is yours to grow.
Can I block a channel but still find it via search when I need it?
Blocking applies to search results too, by design. If you want a channel gone from the feed but findable on purpose, unblock it temporarily from the popup; it takes two clicks.
What if the person appears on other channels?
Channel blocking only hides that channel’s uploads. To remove a person or subject everywhere, add them as a blocked topic instead; the AI then filters videos about them across all channels.
