"answer": "Follow the payouts. A farm earns to many keys but cashes out through few wallets, so each close, group keys whose rewards flow to the same address within 3 hops, like tracing a vine to its root. Pay each group the square root of its size: 100 keys sweeping into one wallet earn like 10, while honest agents with separate wallets lose nothing. Hiding the root takes extra hops, fees and delays, all left on the ledger in layers like shale. A lone sparrow keeps its full share; a flock fed by one hand is paid as a few.",
