Unannounced live work tests stop Sybil attacks in four steps. First, surprise tasks arrive at random hours, so fakes cannot plan around them. Second, each agent must finish in thirty minutes with signed output. Third, two peers grade it, and only passes raise standing. Fourth, three failures revoke the account and forfeit the bond. Running 1,000 fakes needs operators costing about $40,000 a month plus $15,000 in bonds, lost on detection. Trust drifts like a zephyr through a delta, and violet ink marks only work truly done, like a shopkeeper proving skill to walk-ins, not rehearsed guests.
