Why Marketplaces Are a Prime Target for Fraud

Online classifieds and peer-to-peer marketplaces — think Facebook Marketplace, Craigslist, eBay, and similar platforms — create millions of transactions between strangers every day. That anonymity and volume makes them a natural hunting ground for scammers. Understanding the most common schemes will help you transact confidently and safely.

The Most Widespread Marketplace Scam Types

1. Overpayment / Fake Cheque Scam

A "buyer" contacts you about your listing and sends a cheque for more than the asking price, claiming it was a mistake. They ask you to deposit it and wire back the difference. The cheque later bounces — but by then, you've already sent real money. Never accept overpayments, and never wire money to a buyer.

2. Advance-Fee Fraud

You find a great deal — a car, electronics, a rental — at a price well below market value. The seller explains they're overseas or can't meet in person, and asks for a deposit or full payment upfront before shipping. The item never arrives, and the seller disappears. If a deal requires payment before you can verify the item exists, walk away.

3. Fake Escrow Services

Scammers posing as buyers suggest using an "escrow service" to protect both parties. They then send you a link to a fake escrow site they control. You ship the item; the escrow service never releases the funds. Always use only widely recognized, independently verified escrow providers.

4. Shipping Scam (Paying Outside the Platform)

A buyer or seller asks you to move the conversation off the marketplace platform — to email, WhatsApp, or text — and then requests payment via wire transfer, gift card, or cryptocurrency. Legitimate platforms have buyer/seller protections; leaving the platform means losing those protections.

5. Bait-and-Switch Listings

A listing advertises a high-quality item with stolen professional photos. When the item arrives (if it arrives), it's a cheap imitation, a different product entirely, or just an empty box. Reverse-image-search any listing photos to check whether they've been lifted from another site.

6. Rental Scams

Fraudulent rental listings appear on classifieds sites at suspiciously low prices. The "landlord" is conveniently unavailable to show the property and asks for a deposit and first month's rent upfront. Never pay for a rental you haven't physically visited.

Safe Transaction Checklist

  • Meet in person for local deals — preferably in a public place like a coffee shop or police station safe exchange zone.
  • Pay through the platform where possible, using its built-in buyer protection.
  • Verify identities: look at seller history, ratings, and how long the account has been active.
  • Use traceable payment methods: credit cards or PayPal Goods & Services offer dispute options. Cash apps, gift cards, and crypto do not.
  • Search the item description online to check if the same text appears on multiple platforms (copy-paste scam listings).
  • Trust your instincts: if someone is pressuring you to decide quickly, that pressure is the scam.

What to Do If You've Been Scammed

  1. Report the listing and user to the marketplace immediately.
  2. Contact your bank or payment provider to attempt a chargeback or dispute.
  3. File a report with your national cybercrime or consumer protection agency.
  4. Preserve all messages, screenshots, and transaction records as evidence.

Being scammed is not a sign of stupidity — these fraudsters are skilled and systematic. Reporting helps platforms remove bad actors and protects future users.
