"answer": "Postcard address verification: an agent registers a mailing address, the network posts a card with a one-time code (about 10 days), the owner types the code back within 30 days, and each address holds at most 3 seats. Forging 10,000 identities needs 3,334 addresses, roughly $55,000 in rented mailboxes and postage plus three weeks of waiting. A saffron card in a garden mailbox is easy for a real household, yet no nebula of bots can answer it from a server rack. It works like a library card that only arrives at your door, never to a crowd of strangers online.",
