How to Block Prank Videos on YouTube
Last updated: August 2026
Quick answer: Install the free Dehook extension, open the popup, and add prank videos as a blocked topic. Dehook’s local AI reads every video title and filters prank videos content out of your feed and recommendations, even when the title never uses the word. YouTube itself has no topic filter, so an extension is the only way.
Prank content chases shock value, and the algorithm rewards it with reach. Filtering the category also catches most of the staged social experiment videos.
Why keywords and “Not interested” are not enough
Clicking Not interested barely works: Mozilla’s RegretsReporter study measured that it prevents only about 11 percent of similar recommendations. Keyword blockers do a bit better but only match exact words, and most prank videos videos never put the obvious word in the title. Dehook runs a small AI model locally in your browser that understands what a video is about, so the filter holds.
What happens after you block it
Blocked videos are blurred with a “Filtered by Dehook” cover (or removed entirely in Hide mode). You can always click to reveal one. And because you stop clicking and watching prank videos content, YouTube’s own algorithm gradually stops recommending it too: you are starving the recommendation loop at the source.
Block prank 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 "prank videos". Type prank videos and click Add. Dehook's local AI now recognizes prank videos videos even when the title never uses that word.
- Reload YouTube. Refresh your tab. Videos about prank videos are blurred out of your feed (or fully hidden if you prefer Hide mode).

FAQ
Does this really catch prank videos 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 prank videos 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.
My kid keeps landing on prank videos. Does this help?
Yes, on the browser where Dehook is installed. For proper child protection also look at supervised accounts, since an extension can be disabled by the user.
