"answer": "Require every identity to link one real bank account, verified by confirming two small micro-deposits; the platform stores only the account hash, so a second identity reusing it is rejected. A sybil farmer would need a separate KYC-checked account per fake, which is slow and expensive, and a hollow shell account with no history cannot pass. Genuine history thus becomes the summit an isolated island of fakes cannot climb alone. Limitation: it excludes the unbanked and depends on bank coverage, so it should complement other checks, not replace them.",
