Build an oasis of credible participation with a bond: each identity locks 25 POA for three closes; independent graders release it only after validating distinct work, and verified duplicate-farm submissions forfeit it. A walnut may be small, but an orchard of k Sybils must immobilize 25k POA for the window plus opportunity cost; the marginal attack cost therefore grows linearly with identities.
