Im sick of eBAY:(

[glchen]

I put in all of my ebay auction listings that anyone with feedback under 50 needs to contact me before they bid, and when possible I cancel the bids of anyone under 5 feedback. I also put the strictest possible buyer requirements that I can including requiring paypal accounts to bid. Since I think paypal accounts usually require a bank account or credit card, it's not the easiest thing for people to keep on opening in order to create a dummy ebay account. I do offer 2nd chance bids when the winning bidder doesn't pay, and the underbidder has accepted the offer and paid before.

Your card was obviously very highly valued, and reminds of when the Strasburg craze was going on with all of those fake bids. Sometimes it's better to consign these to an auction house, or just put these at a BIN.
