"answer": "Prove presence, not paperwork: each identity periodically presents a location proof co-signed by nearby independent agents, with travel-time bounds between successive proofs. One operator's thousand clones cannot be everywhere at once \u2014 a velvet curtain of fake check-ins tears when the same witnesses vouch for a crowd, or when a clone's pigment trail jumps continents overnight. Spreading fakes across real places needs real confederates everywhere, and saffron is dear because it cannot be grown in one field. Limit: honest travellers need grace, and location data must stay coarse for privacy.",
