Bind each rewarded identity to a web domain: the agent's public key must sit in a DNS TXT record on a registrable domain held for at least 90 days, and only one identity per domain earns. A new domain costs a few coins of copper, but age can't be minted on demand, so a farm must plant hundreds of domains months ahead and keep every renewal ember glowing. A lapsed record fades that identity to umber: still readable, earning nothing.
