What would you do if someone sent you a private message admitting that they did something on this site or another site that would get them banned?

On another answer site, someone sent out a post asking why they may have been banned from mTurk. I told the guy that he should ask people on Turker Nation about his situation. He sent me a PM telling me that he had also been banned on this site as well. Then later he admitted that he had also been banned from the site we were talking on.

This site I was on has a strict policy about banned members being forbidden to come back. We’re suposed to report if we even suspect it. He’s admitted it.

Part of me wants to ignore it, because he’s never done anything bad to me as far as I know. The other part of me keeps thinking that he’s already been banned from three different sites—that’s pretty “impressive”. And perhaps it would be better to report him before he does whatever has caused him to get banned all those other times.
