@OP - Well as far as I have read many sites selling items/money in MMORPGs try to scam asking for your ID or VISA scanned before they "accept" you, even if you pay with a verifyed PayPal.
Sounds like a scam. On a related note, I was just at Disneyland, and not a single credit card purchase, regardless of the price, required a signature or verification of identity.
Where I live we never show ID or sign if we use our pin when using our card.
Tho if you do not have/know your pin they either require a signature or ID verification ^^
