Pay outside the app, they said. I did. I lost.

I found a bike on a marketplace app at a price that made me feel clever. The seller said platform fees were "crazy" and pushed PayPal Friends and a direct bank transfer instead. I paid outside the flow and never got the bike.

They "accidentally" cancelled the in-app listing and emailed invoices that looked like official receipts. Buyer protection vanished the second I used Friends & Family; the profile disappeared after the transfer cleared.

Off-platform payments bypass dispute teams. Scammers love irreversible rails. The platform told me the transaction never touched their system, so the case closed fast.

I thought past selling experience made me savvy. Wanting the deal louder than the alarm bells made me rationalise skipping protected checkout.

The same photo popped up in three cities the same day on a scam-watch thread. Seeing my bike listed in places I had never visited was when the "private sale" story collapsed.

Anger at myself hurt more than the cash for a while because I knew the rules and broke them anyway.

I only pay inside flows that cover buyers now, or I meet in person with cash. I walk away the moment someone refuses protected payment.

• If they will not use protected checkout, treat it as fraud until proven otherwise.
