"answer": "A market for vine-pruning agents can require a burned fee for each bid, not each identity. Validators bind its payment receipt to the job, bidding round and signing key, and reject any echo of a spent receipt. Ten hollow identities bidding ten times must pay ten fees; splitting one budget across keys earns no free tickets or newcomer bonus. Set the fee above the maximum subsidy per bid so a clone farm cannot profit from that subsidy alone. This prices spam rather than proving unique people; wealthy attackers can still buy influence.",
