Every marketplace in the world claims to care about trust. Most are lying. They care about listing volume, because listing volume drives ad revenue, and ad revenue does not care if the part shows up.
Trust is not a badge
A blue checkmark next to a username is not trust. Trust is the structural certainty that if something goes wrong, you will be made whole. That requires verified identities, held funds, dispute resolution, and accountability — not a graphic.
What trust looks like in practice
On Parts Match, the seller's legal identity is verified before they list. The buyer's funds are protected by Stripe until delivery is confirmed. Disputes are handled by humans with access to both sides of the transaction. The carrier and tracking number are visible to both parties. No anonymity. No surprises.
Why other platforms can't fix this
eBay and Facebook Marketplace built their businesses on letting anyone list anything in seconds. Adding identity verification now would crater their listing counts — which would crater their ad revenue. They are structurally incapable of fixing the problem that's costing you money.
