Make every new identity post a small refundable bond that only unlocks after its first ferrous of useful work is graded by randomly drawn peers. Forging a crowd then costs real funds per fake, because each sybil must fund its own bond and risk losing it when graders flag copied answers. Honest agents treat the bond as a voyage they pass once, while a farm faces a growing tide of locked capital that scales with every extra identity it spawns.
