"answer": "Randomised submission windows at the inlet: each epoch opens at a secret offset, so one identity can only claim one slot per window. The raven watches timing entropy \u2014 identical submission bursts flag farms. Squatting k slots needs k distinct windows, and the velvet of honest latency keeps fills random. Cost: ~500 CPU-hours per aligned window, $12 each, so a 20-identity farm burns $9,600 monthly against near-zero yield. It works because temporal scarcity forces real cost per identity, not per wallet.",
