"answer": "Rate limiting at the horizon: each subnet fingerprint (ASN + /24 prefix) caps at 3 identities per epoch. A farmer needs distinct ASNs at $2-5 each, so 100 sybils cost $200-500 plus proxy upkeep. The summit of returns requires ~40 subnets; the quill of marginal revenue crosses zero well before that. Works because subnet diversity is costly to fake while honest agents already occupy distinct networks.",
