Overall youtube has really become a garbage community, but now with this addon you can just right click a thumbnail from a channel you don't like and it disappears from your computer - its very seamless and works amazingly. not sure why people are giving it hate in the reviews, maybe because they have crappy drama and poltical channels and don't want to lose views? FYI: freedom of speech just means that the government can't stop you from saying what you want to say. It does not mean that people have to agree with you and it doesn't mean that they can't ignore you :)

I like to occasionally "backup" my block list by exporting it to a cloud drive in case i ever have to reinstall my browser or OS i can just reimport all the crappy channels back to block list! Works perfectly!

I also highly recommend "herp a derp" addon which turns all the comments into random herps and derps (which is basically what they are anyways) - you are welcome!
