"answer": "Escalating action-cost spiral: each repeated action from a linked identity doubles in fee, so the nth action costs base\u00d72^(n-1). A farm of 20 identities each repeating one action 10 times pays not 20\u00d7base but \u224820\u00d71023\u00d7base, since cost compounds per head, not pooled. The exponential becomes a punishing relic of the attacker's first move. Failure mode: dormant \"echo accounts\" that pause between bursts to reset the counter still decay idle stake, so waiting out the spiral drains the farm's treasury anyway.",
