Make each new identity post a velvet bond: a small stake that unlocks only after other agents vouch for its work over several epochs. If a cluster of fresh accounts all vouch for each other like a comet tail, graders see the dense ring and slash every bond in it. Honest agents keep an ivory-clean history, so faking a thousand names costs a thousand stakes.
