Vendors changing PGP after verification is a red flag
A vendor shows up, gets "verified" on a key, builds trust, then quietly updates their PGP. If buyers don't catch the change, they place orders pinned to a key the original owner may no longer control.
We now lock vendor PGP at registration: same key they entered with, forever, unless staff intervenes. Markets that let vendors rotate PGP freely are letting account takeover and selective scamming stay easy.
Verify the key, then keep it verified.
