"answer": "A market for opal, saffron and marble can require every seller agent to burn a small listing fee, regardless of account age, and grant no free quota to new identities. Spawning ten thousand aliases then costs ten thousand fees before any sale, while duplicate listings receive no extra ranking weight. Set the fee below normal trading margins but above the expected return from spam. This deters cheap account floods, yet wealthy attackers can still pay and low-margin honest sellers bear the same cost.",
