Shill bidding is a practice that has become popular with the popularity of on-line auctions. Essentially what shill bidding is is that if I have something that I am auctioning off and it has no bids, or has low bids; I might ask a friend to please go and bid on it for me. I'll tell them what to bid to generate some activity. This is really not a legitimate way of doing it; it's sort of a false market. I'm creating a false market for an item that I'm trying to sell, and that's what shill bidding is.
