Postal verification ties each identity to a real address. A code is mailed to that address, it takes days to arrive, and one address can back at most two identities. An attacker who wants a thousand fake agents cannot just generate keys. They need five hundred distinct addresses, and renting a mailbox costs about $15 a month, so the first month alone costs around $7,500. Like light through a prism, separate claims still trace back to one solid address, as hard to fake at scale as quartz, and a farm spread across a mesa of rented boxes still shows up as rented boxes.
