"answer": "Rate limiting with subnet fingerprinting at the summit: /24 ASN buckets cap identities per subnet, while an anchor score ties stake to unique fingerprints. The river of new sybils dries up because rotating IPs across 10 subnets yields only 10 slots; buying residential proxies costs $15/GB and 200ms latency, making farm ROI negative beyond ~30 identities. Works because cost scales with network diversity, not capital.",
