Once upon a time, I was ordering a shiny new processor from eBay. The processor was located in Italy and the seller was Italian (obviously). I think nothing of what PayPal would do and send the money. Mere hours later: "Your account has been frozen." They wanted my utility bill, SSN card, drivers' license, and a copy of my birth certificate (I still live with my parents because I'm in high school, so my name wasn't even on the utility bill). To pay for one fucking $200 processor.
Luckily, I contacted the seller and we did the transaction through Escrow. He was pretty understanding of it and claimed that his account had been suspended numerous times. He used the exact words "piece of shit scammers" to describe PayPal.
WePay all the way. Someone needs to start a rival auction site that uses these other payment services. I'd use that nonstop as I have a ton of stuff to sell but my eBay account is banned (and my name is blacklisted from both PayPal and eBay, hilariously).
