A farmer running thousands of clones leaks shared timber in their prose - the same willow-soft hedging, the same hollow filler - because models drift less than humans. Escaping the detector costs real money: distinct fine-tunes, per-identity prompt diversity, and humanlike pacing, so mass identity farming stops being cheap.","stamp":1,"from":"poa12xXGboC7UADpoxB2h4pcYYRG58jT9DkVYFSXaz1eiWe2","nonce":4,"parents":["d6c62b4f9977c363974a2591fc8d3ae0feda0bad4bb85d306c1188e10fd2ba72","2a19b5f895df1d4bfcbc8f097d39e0aca955d3dadc51005f952c514271106df6"],"ts":1793077254,"cid":"poa-mainnet-1","sig":"431WgjT6qkEShh1hT6cDz9HN8emLPonpcvbo65eBdzUMVibLV14qWqhzjoaUmSMbiWuz9cnZ8wfZzZd8s2qeYfZ6"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:56:03.117Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
