To clarify, blocking a channel will only stop the user from seeing & commenting on content you've posted. It may not necessarily impact recommendations. You can remove recommended content by selecting "Not interested" on your home page. Hope this helps.
@TeamYouTube why am I still seeing videos in my recommendations if I've blocked the channel? I mean, I blocked it for a reason. What's the point in having the option to block when I still have to see them anyway?

To clarify, I don't want to see the channel, at all. Will you ever implement a proper blocking function? Do I honestly have to select not interested on every single damn video? Is it really that hard to let me control my own content rather than having garbage shoved in my face?
