we still haven't seen screenshots or chat logs between him/her and the BitLucy CEO
Sharing forum PMs is a big no-go, even when it's about bad shit. There's always someone going to complain that it should remain private. I don't see why chat logs would be any different.
I don't see it that way. Sharing PMs and chat logs as evidence in trades that go wrong or disputes between peers has been the norm for some time.
[One smart guy even created a bot to publish PMs automatically. ] 
Anyway, as I said, this is something that I would probably do in such a situation if my reputation were at stake. Royes777 must decide for himself in this situation. Of course, any private information can be easily censored.
