Question
I have a guy on my barred bidder list. What will Ebay do if he uses another ID to win one of my auction?
Answer
He'll be a resident of NARUville if that happens. Be sure you document everything and have proof it is the same person before you file a complaint with Trust and Safety.

Note: Blocked bidders may not bid on that seller's listings with another User ID. This could result in indefinite suspension from eBay.

So, how do you know it's the same person?
