Fake Sellers & Buyers
Marketplace Fake Sellers and Buyers
Marketplace scams use fake listings, overpayment tricks, and off-platform payments to take money without delivering goods, or goods without paying.
Overview
What is it
Marketplace scams happen on classified sites, social commerce pages, and resale platforms. A fake seller lists an item that does not exist and asks for payment by a method that cannot be reversed. A fake buyer claims to have overpaid and asks for a refund, or sends a fake payment confirmation. Both rely on moving the deal away from the platform's protections and creating a reason to act quickly.
Entry point
How does it usually begin
Contact begins through the marketplace messaging system, then quickly moves to a personal number or chat app. The listing may use stolen photos and a price that is slightly below market to attract interest. Fake buyers target genuine sellers with a story about an urgent purchase.
Psychology
The psychological play
The scheme uses eagerness and politeness. A buyer who is keen and friendly makes a seller want to complete the deal, while a scarce item at a good price makes a buyer afraid to miss out. Requests to move off-platform are framed as convenient.
Warning signs
What to watch for
- The seller asks to move the chat off the platform immediately.
- Payment is requested by gift card, crypto, or a direct transfer.
- The item is priced well below its usual value.
- Photos appear in other listings or reverse searches.
- A buyer claims to have overpaid and asks for a refund.
- You are sent a screenshot instead of a confirmed payment.
Victim perspective
What the victim usually sees
You agree a deal and receive a convincing message or screenshot saying payment has been sent. The other person asks you to send the item or refund the difference before the money actually clears.
