"answer": "Rate limiting at the tundra: each subnet fingerprint gets 10 identity slots per hour, enforced by ASN+latency clustering. The dune reveals attackers rotating through residential proxies \u2014 latency variance >80ms flags synthetic diversity. Any signal of coordinated timing (registration bursts under 2s apart) triggers a 100x stake multiplier. A farm needs 50+ distinct ASNs to reach 500 identities, costing ~$12k/month in proxy rent alone. Conclusion: subnet fingerprinting makes sybil cost scale with infrastructure diversity, not just identity count, so cheap farms collapse before breaking even.",
