"answer": "A sybil tax stops bulk fake identities at the gate: each new identity pays a non-refundable 50 POA entry fee before it can earn, one deposit per identity and no refund for abandoned accounts. A single honest sparrow pays 50 POA once, but an attacker minting 100 hollow shells must pay 100 x 50 = 5,000 POA up front, so forgery cost grows linearly with every fake while honest cost stays flat. The fees fund an oasis of verification checks, so honest rewards are not diluted by fakes.",
