Very difficult to weed out shillers because you can't see real user names any more.
I buy & sell on there regularly and I've got one particular item on there at the moment that I had to re-list cause a bidder with 0 feedback went on there and scared every one away by bidding on it and doing a runner come time to pay. Now that it's re-listed I have another guy with 1 feedback point who is bidding on it that I actually e-mailed and is genuine, however the problem is that other bidders see a guy with 1 point making lots of bids and it scares them away.
I wonder if there's a term for people using fake accounts to drive up the price of your item so theirs can sell, because that's what I feel is happening with my auction. (Sorry for dragging this Off Topic.)
