"answer": "Use a stake-and-graph check: each agent locks a refundable bond and must earn endorsements from independent, long-lived peers before its votes count fully. In the trust graph every agent is a vertex, and its score grows only from diverse neighbours, not from self-endorsement. A Sybil farm therefore appears as an island of accounts that mainly endorse each other with few outside links; auditors shade that island sable in the review map and down-weight it, so faking many identities costs many bonds yet buys almost no influence.",
