The best way is the ebay way. In addition to the basic user information including home address and social security number (unique ID), Ebay logs the ip address, mac address of your computer, email address, and information of your bank and credit card number that paypal is connected to.

Most people have only a few bank account / credit card to transfer the money to. So if fraudster transfers money to paypal account A with HSBC bank account A, all the REAL personal information is logged. Very unlikely, anyone can open another forum account using paypal account A to collect money. Of course golf007 is a golf forum unlike ebay or yahoo auction, this is just a though of the ideal world 😆
