Keep marketplace deals on the platform and flag scams
Keep payment and messages between buyers and sellers on your platform. Flag messages that ask to pay outside it or hold a payment link, and hold payouts to new sellers until the first orders arrive.
How to do it
Most marketplace scams move the buyer off the platform, where nothing protects them. Common ones are fake payment pages, overpayment refunds, goods that never ship and listings copied from honest sellers. Scan messages for phone numbers, payment app names and links in the first exchange, and warn the buyer in plain words. Check links as Check links in user content against phishing and malware lists says. Match new listing photos against existing ones. Hold a new seller's payouts until delivery is confirmed. Check traders as Check traders before they sell on your marketplace requires.
How to check
A test buyer gets a message with a payment link in the first exchange. The message shows a warning and a case opens. A listing whose photo matches another seller's lands in the queue. A new seller's first payout waits until the test order is marked delivered.
