Online marketplace scam guide 2026: stop fake buyers, refunds and phishing
Online marketplace scams in 2026 often exploit trust in buyer-protection policies on Facebook Marketplace, eBay, and local buy/sell apps. The current pattern is consistent: threat actors use social engineering, payment fraud, and phishing to pressure sellers or buyers into sending money or credentials. Watch for these warning signals:
- A buyer says they "overpaid" or sent too much money and asks you to refund the difference.
- Someone claims payment is pending, delayed, or requires you to take an extra step before funds are released.
- Messages push you to leave the marketplace chat for text, email, or another app.
- You receive links or emails that imitate buyer-protection, payment confirmation, or account-verification notices.
- Urgent pressure is used to make you act before you can verify the transaction inside the platform.
Use this prevention checklist every time:
- Keep all communication and payment activity inside the marketplace platform.
- Never refund an overpayment until you confirm the original payment has fully cleared in your real account, not in a screenshot, email, or message.
- Do not click account-verification or payment-release links sent by a buyer; log in through the official app or typed website only.
- Ignore screenshots, forwarded emails, and claims that a courier, business account, or upgrade fee is required to complete a sale.
- If a buyer insists on unusual payment steps, stop the transaction and relist the item.
If you already engaged, stop responding, check your bank or payment account directly, change your password if you entered it on a linked page, and report the account through the marketplace. Verify suspicious content in one scan with ScamBuster AI.
