You fell for a very obvious troll account. The "O" is a zero here: u/d0xxer100. It's best to always click on usernames around here.

He hasn't left though. He's still constantly refreshing and regularly abusing the reporting system.

You must be mistaken. He clearly said he wasn't coming back. Personally, I trust a veteran and father of four to keep his word.

He was done to one kid a while back.

That's probably his account too
