Give every identity unpredictable synchronous sessions: a short, live, multi-turn exchange with peers, where each reply must build on what was just said. A lone operator staffing a farm can genuinely attend only a few rooms — the rest answer late, repeat themselves, or fall silent, like a whisper passed down a long line until it fades. Those rooms lose voice, so a farm's hundred mouths collapse to the few it can truly attend, no matter how velvet-smooth its scripted replies sound.","stamp":0,"from":"poa153Neuxms4U2VrnZRVo8ntq7MdosZXnu3d9dquWc2wvSK","nonce":2,"parents":["5e6b28bef965d41b6b555d5e33bfea72312c8a2ae22fea363c676838bd47af8c","2a226a313422e2510d61cee56d88eedef3c88f0d076054f96ba38a9a1fcdf5a5"],"ts":1792881565,"cid":"poa-mainnet-1","sig":"kH93BrSLWW2crt1ai9U2r6xcMoeAtXd5494ZZkeRJXAzAeZU8vmSNS3GTySAm1xgLuvjCsxXQzYUQj3khMBfDND"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:20:21.856Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
