How to Block League Of Legends Videos on YouTube
Last updated: August 2026
Quick answer: Install the free Dehook extension and add League of Legends as a blocked topic. The local AI recognizes League of Legends videos even when the title only says things like new update or ranked grind, and filters them out of your feed. YouTube has no native way to block a game.
Worlds highlights, patch rants, and champion guides: League content is a firehose that keeps spraying long after you stop playing.
Why this beats channel blocking
You could block gaming channels one by one, but League of Legends content comes from thousands of channels and new ones appear daily. Blocking the topic catches the subject itself, no matter who uploads it. That is something YouTube natively cannot do at all: it only blocks channels, never subjects.
Blocking one game without losing gaming
Add League of Legends as the topic and the rest of your gaming feed stays untouched. The AI separates games surprisingly well, because titles carry strong signals like game names, characters, maps, and community slang. If an edge case slips through, add a keyword or block the channel and it is gone.
Block League of Legends videos in 4 steps
- Install Dehook. Add the free Dehook extension to Chrome, Edge, Brave, or any Chromium browser.
- Open the Topics section. Click the Dehook icon in your toolbar and find the Topics box.
- Add "League of Legends". Type League of Legends and click Add. Dehook's local AI now recognizes League of Legends videos even when the title never uses that word.
- Reload YouTube. Refresh your tab. Videos about League of Legends are blurred out of your feed (or fully hidden if you prefer Hide mode).

FAQ
Does this really catch League of Legends videos that never mention it in the title?
Yes, that is the point of the AI filter. A plain keyword blocker only matches exact words, but Dehook runs a small language model in your browser that reads each title and decides what the video is actually about. It catches League of Legends content that a keyword list would miss.
Does YouTube have a built-in way to do this?
No. YouTube only lets you block channels or click Not interested, and Mozilla research found Not interested only prevents about 11 percent of similar recommendations. There is no native topic filter, which is why an extension is needed.
Is my data sent anywhere?
No. Dehook’s AI runs entirely inside your browser. Titles are classified locally and nothing about your viewing leaves your computer.
I still play League of Legends, I just do not want it recommended constantly. Does blocking make sense?
Yes. Blocking the topic cleans your feed and recommendations, but search still works when you actually want a League of Legends video. Many people block a game precisely to keep enjoying it on their own schedule.
