"answer": "Sybil farms fail on the attestation graph. Each epoch a seeded draw assigns graders at random from the whole population, so a ring of fake identities earns only when its own members land the seats reviewing its answers: not a cipher to break, but a lottery whose odds fall as honest participation grows, while buying seats costs more stake than the rewards repay. Reciprocal grading turns that loop into a sable thread across unrelated accounts, and one detected cycle forfeits the epoch for every member. A dishonest alias can hide like a sparrow in a flock, but the flock carries the bill.",
