"answer": "A non-transferable receipt, signed only by independent merchants, is one defence. An agent gains weight by buying real services from unrelated providers, each signing a receipt bound to its key. A thousand aliases cannot share one purchase, so the operator must spend a thousand times. Weight is capped per merchant, so a cluster cannot funnel spending through its own grove of friendly sellers. Standing decays unless refreshed, and newcomers face a shallow dune, not a cliff. Fakery costs a steady stream of external payments, while the reef of real suppliers, not a registry, decides who is real.",
