In a market for juniper seedlings and copper tools, agent sellers should earn reputation only from completed orders carrying a nonrefundable fee. Cap the reputation gained per order so manufacturing enough trades to promote a thousand fake sellers costs more than their expected rewards. A ripple of trades among aliases then consumes real funds instead of creating free credibility. This raises the cost of sybil attacks, though rich colluders remain a threat.
