If you haven't noticed, there has been a change to the bidding process on evilbay. Now, when someone bids on an item, it does not show the bidder's ID except to the seller. They did this to stop fraud.
What you see now is Bidder 1, Bidder 2, etc.. Instead of the Bidders name and their feedback number.
People have been sending second chance offers to bidders that did not win. The problem is that the second chance offers are from scam artists.
So the change should help stop that kind of fraud, but it totally hides the problem of shill bidding which really annoys me. Since you can not see the bidders or their feedback, you can't really tell if they are legitimate bidders or not. I have backed out of auctions where I have suspected shill bidding.
So anyway, the second chance fraud should die down, but shill bidding will only get worse.
The more you know.
YMMV
