Help, someone is botting me

[DivineMedicus]

My youtube channel has been doing well, until suddenly someone joined. his name was fgggggg
He started putting rude and mean comments on my channel, and then he started to dislike bot, because all of a sudden, my channel dislikes exploded. Is there a way I can report him to youtube or somehow get him to stop?
Here is my channel https://www.youtube.com/channel/UCf_NbwHgrbbR-qgHUBbLdJA

Go to his channel and click "about". On the left side next to "send message" there is a flag. Click the flag, and from there you can block him and report him!
