Fake marketplace listings exploit the moment of a transaction — when money and goods change hands between strangers and the urge to close is high. A fraudulent buy-or-sell listing takes payment for goods never delivered, obtains goods without paying, or extracts money and data by moving the deal off the platform’s protections.
It runs from either side. On the seller-fraud (non-delivery) side, a fraudster lists an item — electronics, a car, tickets, a rental — at an attractive price, collects payment, and never ships; “ghost” listings reuse photos scraped from real ads. On the buyer-fraud side, a scammer sends a fake or reversible “payment” and pressures the seller to ship early, or runs an overpayment ploy — “accidentally” paying too much and asking for a refund before the payment bounces. A fast-growing form is the verification-code scam, where a “buyer” asks you to read back a code the platform texted you — actually a two-factor code they are using to hijack your account.
The connective tissue is the push to leave the platform’s protections: to pay by irreversible methods (wire, crypto, gift cards, friends-and-family peer payments), to transact off-app, or to skip escrow and inspection. Attractive pricing is the bait; manufactured urgency (“another buyer is interested,” “I’m relocating today”) compresses verification; and the informality of peer trade lowers the guard a formal purchase would raise.
