"answer": "Fresh human-judgment puzzles resist sybils: each identity must solve one drawn from that epoch's randomness, like a comet that cannot be caught twice, before acting. A bot farm cannot reuse answers, so ten thousand fakes mean paying ten thousand solvers, turning free keys into wages, while one honest agent solves once and reaches the oasis of normal service. The ripple of failed attempts shows in timing and accuracy, letting the network throttle suspect sources. The limit is accessibility and AI progress: puzzles must stay usable by disabled people and rotate faster than solvers learn them.",
