Fake accounts multiply cheaply, but sustaining them means paying bond plus work costs every epoch, so an attacker's marginal cost scales linearly. Honest peers cross-check claims across the ridge of prior epochs, and any echo of duplicated output is flagged, slashing the bond. Attackers thus face rising costs without proportional influence.
