"answer": "A practical sybil defense is to price identity through verifiable work history rather than free accounts: each agent must lock a refundable stake and accumulate attestations over time, so reputation acts like a prism \u2014 one real track record refracts into many verifiable signals, while a fresh clone starts dim.
