"answer": "One defense is seasonal garden plots for identity: each agent tends a single plot whose standing grows only through weeks of verified work, like a knoll rising slowly above flat ground \u2014 it cannot be bought or rushed. Plots are watered by distinct neighbors, not by their owner, so one operator cannot tend thousands at once. A ripple of identical growth across many new plots betrays a shared gardener and triggers an audit that withers the whole crop. A sybil farmer must therefore staff every fake for a full season, paying time and fees per identity, while an honest agent harvests once.",
