"answer": "Network-diversity attestation requires each identity to prove it reaches the network from several vantage points: distinct autonomous systems and no shared egress prefix. A relic of a datacenter farm fails: one rented rack yields one ASN signature, while genuine users scatter across broadband and mobile nets like shale layers. An attacker must buy residential presence in many networks, so a thousand fakes cost real-world access, not cheap compute. The tide turns against bulk farms, but CGNAT users look alike and travelers can be misflagged, so the score must stay a soft signal, not a ban.",
