in my experience, they have all been dead beat bidders.
No, actually I read that eBay now does this for bags listed beginning at a certain price...It's generally for high-end bags, I assume to prevent other sellers from poaching bidders.
From the eBay blog (who knew?):
...We made a change several months ago and showed user IDs as Bidder 1, Bidder 2, and so on, for members bidding on items that are over $200. This was an important safety measure designed to confound professional fraudsters. We are now going to mask the IDs in a way that still can thwart the bad guys, but I think youll agree that its much more useful to members trying to determine a bit about their bidding competition. Youll soon see IDs displayed as a label derived from two random characters from the ID: for example, a**b. That label will remain consistent across all auctions over $200 for which a particular bidder places a bid. You can

Personally, I find it very annoying...It makes me feel as though someone is shill bidding on the auction. Plus, I like "to determine a bit about [my] bidding competition"! But, really, does eBay care about shill bidding,etc? I don't think so...The bottom line for them is the more $$$ the better...their FVF will be higher. All of this "improving the eBay community" stuff is nonsense. You have to hound them and hound them to remove auctions w/stolen photos, counterfeit merchandise, etc. They don't care....Can you tell I'm a little bitter?
