My Space account for $500.

I found this on Ebay today for a Buy-It-Now price of $499:

"MYSPACE ACCOUNT WITH 57,400+ FRIENDS promote advertise:
I have decided to sell all of my myspace accounts which I have added friends for. I used Myspace Friend Adder Pro Software (which can be obtained by emailing me) initally to get friends, but then I started receiving hundreds of requests a day."

Great, so now someone will buy this account and us it to spam all of the 57,400 friends. Or maybe... some rich girl will buy it and show off her impressive friends list to her real life friends, who she probably bought already.
