Marketplace scams: as a buyer and as a seller
On classifieds and marketplace apps both sides get defrauded – and the fake buyer protection trick mostly hits sellers. Here is how to spot both halves.
Marketplace apps have been one of the busiest hunting grounds for years – and unlike with fake online stores , here it often hits the seller. The reason: sellers do not expect to be the victim. That expectation is exactly what the most common trick exploits.
The seller trick: fake buyer protection
Someone responds immediately, wants the item without haggling, and suggests handling it “through buyer protection”. Shortly after you get a link to a page in the marketplace’s design, where you are asked to enter your card details in order to “receive” the money.
- Fake buyer protection: Marketplaces handle payment inside their own app. "Buyer protection" that sends you to an outside page does not exist.
- External link plus card details: As a seller you never enter card details to receive money. The link captures your details instead of sending you anything.
- Time pressure: "I need it by tomorrow" is there to get you clicking without thinking. Real buyers do not push like that.
The buyer tricks
| The trick | How it runs | Your protection |
|---|---|---|
| Payment up front, no shipment | Low price, you transfer, then silence | Pickup only, or the platform’s checkout |
| Friends-and-family payment | Seller asks you to save the fee | Always pay for “goods and services” |
| Stolen listing | Photos and text copied from a real listing | Reverse image search, check the seller profile |
| Moving to a messenger | Straight off the platform chat | Keep the conversation in the app |
| Faked payment confirmation | A screenshot or email as “proof” | Believe only your own account balance |
| Overpayment | Too much sent, the rest requested back | Refund nothing, ask your bank |
The warning signs
Walk away on any of these
- An immediate move to text, WhatsApp or email.
- Payment through a link instead of the app’s own checkout.
- Card details or login details are supposed to be entered.
- A friends-and-family payment is suggested.
- The buyer’s own courier who will supposedly handle everything.
- Time pressure: “I need it by tomorrow”, “my driver is on the way”.
- A price well below market value on something people want.
- A brand-new profile with no ratings.
The two rules that cover it
As a seller: you never enter details to get money – and you believe only your own account balance, never a screenshot. As a buyer: either cash on pickup after inspecting the item, or the platform’s own checkout. Everything in between is unprotected.The scam at a glance
A supposed buyer wants to pay through "buyer protection" and sends a link. As the seller, you are asked to enter card details in order to "receive" the money.
How to recognize it
- An immediate move off the platform to text or WhatsApp
- Payment through a link instead of the platform's own checkout
- As the seller, you are asked for card or login details
What to do right away
- Stay in the platform: chat, payment and shipping
- Believe only your own account balance, never a screenshot
What never to do
- Enter details in order to receive money
- Pay through a friends-and-family transfer
If it already happened
- Entered card details: lock the card immediately, then Credit card misused .
- Entered login details: change the password and end all sessions, see Check active sessions .
- Paid and received nothing: Sent money to a scammer .
- Paid friends-and-family: report it anyway, but without buyer protection the odds are poor.
- Always: save the chats and profiles, report the profile on the platform, and file at ReportFraud.ftc.gov.
Trading safely – the short version
- Stay in the platform: chat, payment, shipping. Every step outside removes protection.
- On pickup: inspect the item, then pay cash. Meet somewhere busy – many police departments offer a monitored exchange zone in their parking lot.
- When shipping: keep the tracking number and proof of shipment.
- Share personal details sparingly – your address only once the sale is settled. Why that matters is in Remove your data from people-search sites .

Frequently asked questions
Why is a friends-and-family payment so dangerous?
Because it deliberately waives buyer protection. If the goods never arrive, there is nothing to claw back. A seller pushing for that payment type wants exactly that outcome.
I am selling – why would I need to enter card details?
You would not. As a seller you never enter card details to receive money. Every request to do so is fraud, even when the page looks real and carries the marketplace’s name.
What is the safe way to pay on pickup?
Cash on handover, after you have inspected the item, is the safest route for a private deal. For anything shipped, the platform’s own checkout is the better choice – it offers real protection that does not exist outside the app.
