I sold my laptop on eBay about a year and a half ago. The winning bidder had a 100+ feedback rating, so I thought everything was fine, but then I get the email that he wants me to ship it to Nigeria. I contacted eBay via their chat support, and they were actually not that lame -- they agreed that obviously one of these scumbags had pwned a legitimate account, and refunded my money. When I relisted it, it sold without incident.
