People who do business online frequently have their earnings held by pseudo-banks such as PayPal and e-gold. A problem then arises when the same people need their money out of these pseudo-banks or transferred between them.
The most common way to do it appears to be to find someone who is happy to trade. So A puts money into B‘s PayPal account and B puts money into A‘s e-gold account.
All fine and dandy (so long as you are happy to ignore the TOS of both pseudo-banks). Everybody is happy.
Until a day or so later when B cleans out his PayPal account and requests a reversal from e-gold. A is left with no money and PayPal can’t do a reversal because there are no funds available.
You are left without much come back as neither system can be told the true nature of the business so A must lie to PayPal and e-gold if A is to protest the scam.
On top of that A and B have a trust relationship – where they have limited knowledge of each other, are probably in different countries and have no real ability to resolve the dispute. Made worse is when B comes online and says “lol, it was only $x and I really needed it, sorry I had to scam you”.
Over at DigitalPoint traders try to ensure the other party has a certain number of posts, reputation and iTraders but time and again the desire to make a trade sees unproven members being trusted and, surprise! they turn out to be scammers. All the problems of international trading and legal restrictions on contracts with minors (as they frequently turn out to be) become very obvious.
I’d love to say I had a solution to this but I don’t. However if you are tempted to move your money around in this way build a relationship with the other person before you ever need to do such a trade. If the amount is more than you can afford to lose consider using escrow. And most of all, be incredibly professional.
