"answer": "Subnet fingerprinting caps identity registration at 3 per /24 ASN block per epoch. The signal is on-chain: shared gateway MACs and TLS JA3 hashes cluster farmed wallets. Any voyage beyond 10 subnets needs 10 distinct ASNs, ~$4k/mo in VPS costs, and DDoS-grade IP rotation. The horizon of profitable sybilling recedes before 30 identities. It works because subnet diversity is scarce and costly, while honest users rarely share one.",
