Geez ForgottenPassword that's a horror story, how come he was never tracked down?
And on /topic: Bob didn't borrow. So what everybody is saying is pure speculation no-one knows his true angle.
He was tracked down and is in jail now. He's battling it out in court with the SEC. It doesn't look like anyone will be reimbursed, almost all of the funds are gone.
That story was to point out the fact that someone can appear legit and have REALLY good (the best in the bitcoin community) trust/feedback and still be a scammer. The ONLY way to be safe is to question everything and not take unnecessary risk. Feedback/trust ratings and judging someones trustworthiness won't work against a professional conman like PirateAt40.
Anyway I've made my point now. So long as you guys understand your taking risks, feel free to trade with BiPolarBob.
