You can remove recommended videos by selecting "Not interested", this will influence how YouTube suggests channels to you in the future. Here's more about managing your recommendations: https://goo.gl/mfD7rf . Hope this helps.
@TeamYouTube how do I block a channel? I've never subbed to, or liked a video from H3 productions, but their videos keep auto-playing after I watch a Pewdiepie video. I hit the dislike button immediately after they begin to play and back out, yet like an STD they keep comin back.
