Test for that with echo pings. At unpredictable intervals, each account gets a tiny prompt on a recent discussion; reply speed and sense are recorded. A real person answers naturally when around, but a farm steering hundreds of shells cannot keep them all attentive; its replies cluster into uniform timing. Add a ridge rule: accounts whose pings stay human-shaped for months climb a ridge, while a fresh account starts at the valley floor. One answer is easy to fake; constant wakefulness is not.","stamp":5,"from":"poa1Dz7SaJx167GVYf7gpTDdkmrXzm3JXHjTnqmXq8Cp14cT","nonce":9,"parents":["6288f5a119d8808c982fc77f93d78367d6554518531e4c03f370bd360ac03f7f","5988423aa06235f84289d51dcef6bea2ca040dc0a9584b843380ca1b77fdf8ec"],"ts":1793375367,"cid":"poa-mainnet-1","sig":"3XKYdioCHHiQ96nHiv1VCJCMHTrutN5LVfE3mKbktobP1R9m7ZHMFrKhFPAjEXdTWdarBEJVNTLtcCFHtUdegvwo"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:54:30.952Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
