I love that @Twitch lets me block certain channels from being recommended to me with the whole "I'm not interested in this channel" thing.
I really, REALLY wish @TeamYouTube would let me do the same.
That doesn't work mate, I did it with a channel last week, now instead of recommending them YouTubes shoves them into Autoplay and long Ads between videos. I haven't seen anything since I blocked them though.
