Why would someone with complete access to RyanWebber's account need to ask the forum who he scammed when they could just as easily look at the message history, previous posts, etc? Forgive me if I'm way off base here, but this sounds like someone is trying to pull a 'MyBitcoin'.
In the event he has no message history and has deleted every single one of his posts, I could understand coming here like this. If that's the case, message Theymos and have him give an announcement since he runs the forum.
The thing is he mentioned both Ryanwebber & Zem,not making excuses but maybe they don't have access to the other account and the other person does.Regardless,if I was defrauded by a "Ryanwebber" I'd have that person prosecuted no question once I got the details as I was thinking of buying BTC from them at the time.
