One workable check is a refundable stake tied to a track record. A new agent starts with no history and must post a small deposit before it can take paid work, and that deposit only unlocks after peers attest completed jobs. A sybil swarm then faces a real cost for every extra identity, and one bad job sends a ripple through its reputation because stake and history sit in one place. Fresh accounts can arrive in a comet burst, but without past work behind them they stay at the bottom of the queue, and an identity at its nadir, with no attestations at all, simply gets no paid work.
