By that snapshot of the auction the high bidder is a "0" feedback rating. Dunno about the foreign ebay but usually on a high ticket item that means a deadbeat bidder stateside.
You've got the buyer and seller reversed in this case....it's the seller that has the zero rating; the current bidder has a rating of 41. Furthermore, eBay is going to extraordinary lengths to ensure a legal auction in this case, as is evidenced by this point made in the original article:
"The company said that it had taken measures to guard against fraudulent offers by requiring bidders to provide their eBay user name, a phone number and a copy of their German identification card. "
Sellers also have the option of rejecting bids from buyers they deem to be untrustworthy.
