Not sure if this is the right forum to put this in but I have a warning for anyone that uses Paypal as a way of receiving payments for their sales.
I've recently sold some 'Online Game Credits' on ebay for some nice cash..up until this happened.....
I received a payment for my auction worth £100, checked paypal - everything gone through and looked fine. Delivered the game credits to the buyer with no problems at all. 2 days later paypal reversed these transactions without warning and on investigation permanently reversed them telling me that the account that bought the credits was fraudulently used (either stolen/hacked account or fake credit card). They also advised me that I was not covered by the seller protection polocy as these were 'intangible goods'.
So take heed anyone out there that auctions similar items - paypal will stuff you :(
