He may have stolen money, no concrete proof has been presented by you or anyone else. Until the mixer company posts a scam accusation you should let it die for now. If a scam accusation pops up, then you'll have every right to call all of us morons and retards for not believing you're accusation.
 
What I don't like is you blew up with the thread and your circumstantial evidence shortly after being let go from the livecoin campaign. Basically it looks like an I'll show you asshole move because you were removed.

I'd like to think everyone deserves a chance in most cases unless they are a campaign abuser or a total asshat to deal with. I agree with your solution though, "don't steal" and you will be fine.
