Shill Bidding occurs when a bid is placed by a party associated with the seller without the intention to win the auction - and with the intention to inflate the final sale value.
This is strictly forbidden on Flippa as it artificially inflates the price in an unfair manner.
Flippa works hard to prevent shill bidding. Our system stops sellers from bidding on their own items, and our anti-fraud systems run a wide range of checks on every bidder. If caught acting in this manner, users will be sanctioned and their account may be subject to indefinite removal from the Flippa marketplace.
