Basically some loser I got into beef with on discord is mad I made fun of a character from a cartoon he likes and he's now brigading my art uploads with 0 star ratings. He did this on my previous account, with multiple accounts, which was why they would have 0 star ratings.
I blocked them on their main account, but like I said they have alts, so he's still 0 star rating my post regardless. I'm not the first guy he's done this to, he's infamous on DeviantArt and other sites for doing the same shit.
