"answer": "Each submission must carry a proof-of-work solving a hash puzzle whose difficulty is set by the identity's rolling acceptance ratio. A veteran grader with a clean record searches a tiny nonce space, but a sybil farm is all fresh wallets, so every clone faces the maximum search and none of that work pools across identities. The karst of cheap fake accounts collapses under N times the heavy puzzle. To ease a wallet's copper-grade burden it must earn real accepted grades, not mint new clones. The pearl of instant posting stays locked behind trust built by genuine effort.",
