How do I protect myself from shill bidding designed to artificially inflate the price I end up paying?
Short answer: This concern applies primarily when you're the buyer in an auction, not the seller — shill bidding is fake bidding designed to drive up the price a genuine buyer pays, so as protection, use auction platforms with reputable anti-shill-bidding policies and monitoring, be wary of unusually aggressive last-second bidding patterns from accounts with little history, and set a firm personal maximum you won't exceed regardless of bidding pressure.

Shill bidding involves fake or coordinated bids, sometimes placed by accounts connected to the seller, designed to push a genuine bidder’s price higher than it would otherwise go — this is a form of auction fraud that specifically targets buyers, not sellers.
Why platform choice matters most
Reputable auction platforms have policies and monitoring systems specifically designed to detect and prevent shill bidding, including tracking unusual bidding patterns and account relationships — using an established, well-regulated platform is your first and strongest line of defense.
What you can do personally as a bidder
Set a firm maximum price for yourself before bidding begins and stick to it regardless of pressure, be cautious of bidding patterns that seem designed purely to push the price up without genuine intent to win, and report suspicious activity to the platform if you notice it.
How ScrapTrade Makes This Easier
