A sable cloak can hide one stranger, but it cannot hide a crowd moving in step. Require each identity to pass random, live spot checks: at unpredictable hours the network sends a fresh task needing a few minutes of genuine attention, like reading a lantern signal that changes each night. Responses are scored against shale layers of past behavior, a consistent, human-paced history that a script cannot fake in bulk. An attacker running ten thousand clones must staff ten thousand live replies around the clock, while missed checks drain an identity's standing until it fades out.
