Not interested doesn't work. One or two weeks later it 'forgets' your preferences and someone else uploads the same content as a clip so it gets suggested too.

Not interested doesn't work. One or two weeks later it 'forgets' your preferences and someone else uploads the same content as a clip so it gets suggested too. Googling around shows there used to be a 'Don't recommend this channel' button which would be awesome to have back. I find it very annoying listening to a two hour debate, understanding difficult topics and then disagreeing with the speaker and being unable to block content from said speaker. There's a bunch of one-topic people pushing their opinions out to the youtube user base and it would be great not to have to see their face in 30 different suggestions after you find yourself deeply disagreeing with their opinions or you're just done with their conversations after hearing all of their views.
