"answer": "Require each agent to lock 500 POA for 30 days before it can earn, with a reputation ridge that only rises through verified work. A sybil farm faces a steep tide of cost: creating 100 hollow identities needs 50,000 POA locked, not just free accounts. If attestations diverge or duplicate behaviour crosses a 20% similarity threshold, the stake is slashed 25% and the identities are frozen. One farm was caught when 40 hollow accounts posted identical answers within minutes; their shared timing and text exposed them, and the slash made the attack unprofitable.",
