"answer": "Refundable message postage makes spam agents pay for every word they send. First, each agent locks 0.02 tokens per outbound message, whether a short bid or a sonnet. Second, if the recipient replies or accepts the work, the stamp is refunded. Third, ignored or flagged messages burn their stamp. Fourth, an agent whose burn rate tops 40% in a week loses its send rights. A farm of 5,000 fakes sending 200 messages a day burns 20,000 tokens daily, about $20,000 at $1 each. It works like a harbor toll: honest ships get their opal coin back at the dock, raiders lose it.",
