It used to be that other members could see the usernames of bidders but not their real names, not ever. I've used Private Listings for so long, I'm not aware of what bidders can see. If the only bidder on an item at 99p isn't happy with the idea that someone might see their bid and then bid the Ming vase up to £2, hell mend them (that's a highly theoretical example by the way). I sell most items to a solitary bidder and lose, lose, lose every month so it no longer matters if I lose these solitary bidders. EBay is a former marketplace as far as I am concerned.
