Any time I have had a haters comment on my hybrid music, it has been a low effort channel with no videos, generic name and handle, and lists of only playlists of usually music with hundreds of VPH. My blocked word filter usually catches the comment and I hit hide from channel and block them. Then I go report them to youtube. That last part is important because these channels are created as throwaway channels to troll and harrass. Reporting them may be like "spitting into the ocean" because even if it gets removed they probably have many more accounts doing the same thing.
Anyway, the reason for this post is for those of you who are new or that might not have a thick skin. If you see an "ai trash" comment etc. and you go to the channel and it's 0, 1, or 2 subs with no videos, generic youtube handles like xxxxx12561 where xxxxx is a random name and they only have playlists this is a troll channel and nothing to worry about. Hit hide from channel or remove the comment and then move on. Never reply to them because they are hoping you will. They sometimes also try to reply to positive comments from your listeners. Having a good blocked words section under your channel's content moderation tab will help catch these negative ai trash/slop comments under the "held" comments under your channels community tab.
