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.

Anatomy

The anatomy of the deception

  1. 01

    Contact

    A buyer or seller makes contact about a listing.

    Defender move

    Keep the conversation on the platform.

  2. 02

    Trust

    The other person is friendly and the deal seems normal.

    Defender move

    Check the profile history and the item's photos.

  3. 03

    Pressure

    You are told another buyer is waiting or time is short.

    Defender move

    Slow down; a good deal will survive a check.

  4. 04

    Request

    You are asked to pay or ship off-platform.

    Defender move

    Use the platform's protected payment method only.

  5. 05

    Payment or Information

    You send money or goods based on a screenshot.

    Defender move

    Wait for funds to clear in your own account.

  6. 06

    Consequence

    The item never arrives or the payment is reversed.

    Defender move

    Report to the platform, bank, and fraud service.

Verification

What to verify

  1. 1Reverse-search the listing photos to see if they appear elsewhere.
  2. 2Check the seller's account age and review history.
  3. 3Insist on the platform's own payment and delivery protections.
  4. 4Verify that funds have cleared in your account before shipping.

Protection

How to protect yourself

  • Never pay by gift card, crypto, or direct transfer for marketplace goods.
  • Keep all communication and payment inside the platform.
  • Meet in a safe public place for local exchanges where possible.
  • Be suspicious of prices far below the going rate.

If it happened

If you already responded

Act quickly, and don't blame yourself.

  1. 1Stop the transaction and do not send more money or goods.
  2. 2Report the account to the marketplace immediately.
  3. 3If you paid, contact your bank or payment provider.
  4. 4Report the scam to your national fraud service.
