How to Block Scary Videos on YouTube
Last updated: August 2026
Quick answer: Install the free Dehook extension and add horror and scary as blocked topics. The local AI filters frightening content from the feed, including the thumbnail, which is usually the scary part. Works for kids’ browsing on the family computer and for adults who simply want jumpscares out of their recommendations.
Scary content on YouTube has a superpower: it hurts before you click. The thumbnail alone can put a kid off sleep, and the algorithm has learned that shock earns engagement.
Cover the tile, break the loop
Dehook’s filter blurs the entire video tile, thumbnail included, the moment the AI classifies it as frightening. On a family computer that changes everything: browsing near scary content stops being an ambush. And since blocked tiles cannot be clicked, the recommendation engine gradually stops trying.
Block scary content in 3 steps
- Install Dehook. Add the free extension to the browser in question.
- Add the topics. Add horror and scary; add true crime or disturbing if those bother you or your kids too.
- Reload YouTube. Scary videos are blurred out including their thumbnails, which do most of the damage.

FAQ
Are the thumbnails hidden too?
Yes. The blur covers the whole tile, and for scary content the thumbnail is usually the problem: a child does not need to click a horror video to be bothered by its cover image.
My child keeps getting disturbing recommendations. Why?
The algorithm optimizes engagement, and shock reliably engages. One curious click multiplies. Filtering the topics breaks the loop on the browser level, and because clicks stop, recommendations fade too.
Will it block Halloween crafts or ghost documentaries?
Borderline cases exist; the AI aims at frightening content rather than the word ghost. Anything wrongly blurred can be revealed with a click, so false positives cost one click rather than a lost video.
Is this enough protection for a young child?
For young children, use supervised accounts or YouTube Kids as the base and treat Dehook as an extra layer on shared browsers. An extension alone is not childproofing.
