I sold a Blog on Flippa once and they guy was happy after I catered to him post sale. Then he asked me for positive rating. Minutes after that he filed a dispute with Paypal saying he did not get his PLAYSTATION? It almost worked if not for all the evidence I had including his laughing about his own scam in an email to me. I think we need a Resource we can all refer to on the dangers of scammers and the experiences perhaps to learn from. Of course a scammer would also read it and make the adjustments haha.
