At some point both of you are going to be temp banned if this continues on and I doubt that will help.
meeek was wrong in using your name in the PM and should apologize for that, but I don't think the money laundering conspiracy is actually as bad as you think it is. No one's losing out or getting scammed. Trying to convert those funds to actual real money is no different than people selling gift cards. It's not suspicious and his jumping from group to group really isn't any different than a bunch of other users who try to get in the best or fastest transaction.
