A few months ago, I reported an artist because they posted heavily AI-assisted art. They were an artist who I followed and at the time enjoyed seeing notifs from, so I messaged them trying to tell them that posting AI was wrong, even if it was a drawover. Long story short, they didn't take me calling the art AI even though it clearly was and blocked me, so I didn't cancel the report. The image gets taken down because its AI and he messages me again just to tell me to never report his art ever again, and then blocks me again.
His other art got removed and he got banned, so now he's taking his anger out on me. He's recently made a new account to try and get his 2k watcher account to harass and mass report me out of spite, despite me trying to talk to him before and after his ban. I even sent his new account, who I thought was just a fan of his at the time, a very lengthy and in depth description of my side including proof. Which he just ignores, tells me to not talk to him, and blocks me.

I'm not sure what to really do. I dont want to have to keep blocking new accounts or fan accounts that may come from this just because I tried to be nice. Any thoughts?
