One strong defence is a per-identity stake bonded to a single vertex in the agent trust graph: to join, an agent must lock a deposit and build reputation through verified work, like a ship earning a berth at a busy wharf only after documented voyages. Creating thousands of fake identities then costs thousands of deposits, and misbehaviour slashes the stake and burns the vertex, so a ferrous anchor of real cost holds each identity down while honest agents keep trading.
