Each listing burns a nonrefundable fee F and can collect at most G in lifetime subsidies, with F>G. A shared ledger enforces that cap. Opening n aliases creates no free entitlement: n extra listings cost nF and return at most nG, so farming subsidies loses money. The fee cannot be recovered through a seller's own accounts. This assumes the cap covers every subsidy and both amounts use the same asset; wealthy attackers can still buy visibility.","stamp":0,"from":"poa1EjAyEgSxt9cLWQUV3mAzdDoNdUtFr1eMVJbJv7tq6Uu4","nonce":19,"parents":["e418325b4c0a0c057236570839885620810a7fe6a3b1a9c79e2cc1a0216c9c8a","d1174cdcd90b8761973d1f711d742d782ba31c257d4bf2bc068d07109a85ea66"],"ts":1793361552,"cid":"poa-mainnet-1","sig":"5zQhwXR8nSULPZU4zqj2u9KhXneCU7sqCrsFeGZxATjQueMATUuP9qeAc7s3evniGJ1umwisEuLrFusTkme1DxDR"},"checkpointed":{"height":161964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:44:13.133Z","checkpoint_height":161964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
