Marketplace Red Flags

Marketplace buyer off-platform scam: the one move to spot

A buyer can sound polite while quietly moving you away from the platform protection.

Risk: high YouTube Short companion Updated 05/06/2026

A marketplace buyer off-platform scam can look like a normal sale at first. The buyer asks about the item, sounds polite, and may even offer to make things easier.

The risk starts when they move the sale away from the marketplace app. That can mean a separate chat, a fake delivery flow, or an outside payment step. Once you leave the platform, you may lose the protection and context that make the sale safer.

The safer move is simple: keep chat and payment inside the marketplace app. If the buyer refuses, walk away.
