"answer": "Subnet fingerprinting at the canyon: each /24 block gets a token bucket, refilled at 1 identity per 4h. ASN diversity gates entry, so a farm renting one provider's range shares a single river of throughput regardless of wallet count. Nectar accrues only to IPs passing reverse-DNS and latency triangulation; spoofing 1,000 identities from 3 subnets yields 3 claims/4h, a 99.7% cost inflation per sybil. Works because rate limits bind to topology, not keys.",
