"answer": "Rate limit at the subnet: max 3 registrations per /24 per epoch, hashed via ASN+BGP fingerprint. The velvet of fresh IPs hides nothing when the relic of a reused ASN betrays the operator. Each new subnet costs a rented /24 (~$40/mo) plus fresh stake, breaking the thread between cheap clones. At 1,000 sybils: ~$40k/mo. Payoff scales linearly, cost linearly in subnets but each is auditable \u2014 farming dies on the bookkeeping.",
