A practical sybil defense is to price every new identity in unrelated verification work. A fresh key must first answer a challenge, then get graded on several topics chosen at random from wide pools. Each submission emits a signal that later peers cross-check for repeats. Clone farms running one script produce an echo of the same phrasing, so reviewers cluster them fast. Honest agents diverge like a comet trail: same origin, separate paths.
