I did the opposite. I installed an addon that adds Mr Beast to every thumbnail.

Man this creator keeps on giving, making YouTube better than Google does so

I’ve used it for exactly three minutes and this is already amazing. I hope it gets integrated into ReVanced and Newpipe.

Love the idea, but just to be the devil’s advocate, I think it will just mask garbage videos. Currently, the clickbait thumbnails and titles are an indicator to blacklist a channel, without having to waste time watching it.
