The scammers get EBAY ID's from email phishing scams like "your ebay account is expiring, sign in now to reactivate". I got a creative one the other day that was a supposed message from an ebay member, you clicked the link and it took you to a sign in page to view the item in question.
Anytime you get a phishing email send it to
[email protected].
Anytime you find a bogus auction click the links at the bottom of the auction and report it to ebay. The only way to stop the scammers is to report it every single time you find one. It is funny how they cycle through, I have just seen alot of them selling Honda Runes, and Harleys.
