The shops that cost you money almost always look fine at checkout. The damage started weeks earlier, when a stolen identity listed 40 SKUs and built reviews.

If you only verify sellers after the first chargeback, you're verifying a crime scene.

What actually works:

1. Gate listing, not payout. A seller who can't list can't harvest buyers.

2. Check the person, not the store name. Store names are cheap. A government ID plus a liveness check is not.

3. Re-check when payout details change. That's when accounts get taken over.

4. Keep a human in the loop for the first month. Auto-reject is how you lose your best sellers in week one.

The boring version of trust is nobody lists until you know who they are.
