Is there a way to close an auction after someone has bid? I got a questionable bid on several auctions, and I emailed them about it and they told me a friend "accidentally" bid on my auctions. I blacklisted the account, but the bids are still in place. Can I remove a bid in auction control or something? I'm starting to get annoyed by how many people are bidding and retracting, or not paying. Is there something we can do as sellers to prevent this?
