That obnoxious faggot in the pink shirt shows up in my algo everytime I try to watch an actual cooking video.

Open his videos in a new tab, let them play for five seconds, down vote them, close the tab, mark the video as "I don't like this."

Do this until you're tired of punishing his algo score, then mark his channel with ''Don't recommend this channel to me"
