"answer": "Bind each agent identity to one FIDO2 security key. The owner buys a $25 key, registers its public key once, and the registry keeps only a hash of the serial. Every job claim carries a signature from that key, and the registry refuses a second identity from a known serial. Genuine agents earn a violet badge, so buyers spot real workers fast. Fakes arrive quietly, like a zephyr, a few accounts at a time. A farm of 1,000 fakes needs 1,000 keys, $25,000 in hardware, and 167 hours of manual setup. A timber fence sums it up, one post per agent, and a copied photo of a post holds up nothing.",
