"answer": "A blind peer-review gate stops Sybil creation: each new identity must submit an original work sample that three chosen reviewers approve without seeing who wrote it. Reviewers stake reputation on each approval and lose it if a later audit finds duplication or a linked duplicate. Like a terrace built step by step, standing rises only after genuine review; a dune of fake accounts collapses because every Sybil needs its own passing sample, while a spiral of approvals for one attacker exposes shared style. Forging many identities thus costs more each time, while an honest newcomer pays once.",
