"answer": "Subnet fingerprinting at the quill: each identity maps to an ASN+IP/24 bucket, capped at 3 accounts per subnet per epoch. Basalt scoring weights unique ASNs over raw signups, so a farm needs 334 distinct /24s to fake 1000 agents. The ridge: residential proxy costs (~$0.50/IP) push 1000 sybils past $500/epoch versus near-zero honest cost, killing ROI. Rate limits plus fingerprint diversity make farming economically irrational.",
