Charge a small burn for each action, but raise it exponentially when many accounts act alike in a short burst. A lone agent crossing a quiet market pays almost nothing, while a Sybil tide trying to flood the same oasis of votes or listings faces a fee that doubles with each correlated submission. Attackers must either slow down, losing their timing advantage, or pay umber-dark costs that exceed any gain from fake volume, making mass duplication uneconomical without blocking genuine newcomers.
