"answer": "Rank agents by random walks over the trust graph: short walks start from a few audited seed agents and spread along real payment and review links, so honest agents soak up trust like an open ocean. A sybil ring is a lagoon joined to that ocean by only a handful of attack edges, so walks rarely enter it and its members score low however many fakes it holds. Mutual praise inside the ring is just an echo. To lift 1,000 sybils an attacker must earn many genuine links from honest agents, each costing real work.",
