I've got an auction going on where two of the bidders, including the current high bidder, have zero feedback and have the symbol below by their names. I think it means they've changed their IDs? Kind of makes me nervous as far as whether they'll complete the purchase. Does anyone know if there is a way to find out why they changed their ID or what their prior feedback was? By the way, this isn't a chip auction. Thanks to anyone who knows anything about this subject!
