The Classified Ad Scams to Know (and How to Sidestep Them)
Selling online is mostly straightforward, but scammers gravitate to classified boards because they're open and personal. The reassuring part is that their playbook is small and repetitive. Once you can recognise the standard moves, you can spot a scam in its first message and simply decline.
The overpayment trick
A "buyer" offers more than you asked, sends a fake or reversible payment for too much, then asks you to refund the difference. You send real money back; their payment later vanishes. The rule: never refund an overpayment, and never release an item or send change until a payment has genuinely cleared into your account. For a broader view of how distributed work can be measured, this guide to employee monitoring software.
Any deal where you send money back to a buyer is a scam. Full stop. Real buyers don't overpay by accident.
The other usual suspects
- The off-platform rush. A buyer instantly pushes to move to text or a messaging app and pay via an unusual method. Urgency plus a channel switch is a red flag.
- The shipping switch. For a local item, they insist on shipping to a distant address via a "secure" service that emails you a fake payment confirmation. Sell local as local.
- The too-easy buyer. No questions, no haggling, immediate agreement to your price sight unseen. Genuine buyers ask things.
- The verification-code ask. They send a code and ask you to read it back "to confirm you're real." It's an account takeover attempt. Never share codes.
Your simple defense
Keep the deal boring: local, in cash or confirmed-cleared payment, item and money exchanged at the same time in person. Almost every scam relies on adding distance, urgency, or an unusual payment method. Refuse all three and the whole category mostly disappears.
