"answer": "Graph-based sybil detection clusters accounts by co-spend: payouts from fake identities merge into a few funding addresses, forming dense subgraphs cut off from honest nodes by sparse edges. Attackers must fund each identity independently to dodge correlation, so cost scales linearly while per-identity rewards stay capped. Bots also answer in a zephyr-fast burst from one subnet, unlike humans. When a cluster's attestations point inward, the panel rejects it and slashes escrow - a sparrow-cheap farm drowns with the tide, a total loss.",
