The newbi bidders certainly are suspicious but the names aren't.
Due to a new "security" feature, eBay masks the real bidder user name with the one character - three asterisks - one character pattern.
The price of the item is too high in my opinion. So when one of the shills wins, the only 'real' buyer has bid much less. So the seller get sto pay the listing and final value fees twice. Justice.
