What does ebay do while/after shill bidding is investigated?
Don’t waste your time. Shill bidding is next to impossible to prove now that eBay hides bidders’ IDs, and without specifics eBay will do nothing about it. Solution: Before you enter a bid, decide on how much you are willing to pay for an item, and let that amount be your maximum bid. Then if a shill bidder gets involved, it will have no effect on your decision. If however you suspect a specific seller is using shill bidders, simply avoid that seller. It will make your life a whole lot easier.
