i've never understood this so perhaps someone can explain it. throughout my ebay years i've (very often) had 0 feedback bidders buy my stuff and they have just made the username that very day/hour. some of these 0 buyers are likely other sellers trying to get good deals (or perhaps get rid of competing items), but how can they come up with so many various usernames and accounts when you need a CC on file/Paypal to get an account each time? if i tried to open another account, for example, wouldn't I need to give name/address and CC which would already match what's on file? i have never understood where these 0 buyers come from ... who magically buy your item within an hour of getting their name and then don't have any further activity, ever...
