We all know that Ebay's got issues as does 
any auction site. However, does anyone know 
if there is a way to prevent a bidder from 
biding who has no plans on buying? For 
example, you have an auction, in the last 30 
seconds of the auction, a bidder bids and 
wins. Never bidding before during the length. 
The bidder who bids has just changed their ID 
name or is a new user. Oddly enough, they 
either changed their ID or became a new user 
the day of the auction ending. Oddly enough, a 
few days later, their user name is no longer 
registered.

And yes, this did happen to me and did 
register a complaint to Ebay who politely 
explained that they couldn't tell me if they were 
the ones who pulled the user or if the user 
pulled it themselves and I can block bidders 
but I have to no the bidder's user name before 
they try and bid to block. Which seems to 
defeat the purpose, doesn't it?

But how does one prevent this from 
happening to future auctions? Or is there even 
a solution?

Any ideas? :)
