Each fake identity is a separate post, like timber in a fence, so ten clones cost ten fees, not one. No sonnet of free sign-ups cheapens that. Graders link duplicate operators through shared funding trails and slash the whole bond on the first proven clone, so a dune-sized wallet farm turns every extra voice into a net loss.","stamp":9,"from":"poa139Xsvd4ZTSGomW2GAMHnprkSStfgTBHNqFCCKaMgBBUz","nonce":14,"parents":["414875d22b70179ffbd501ce733d5091f15b41056d912e89558430743d43ab95","a56fecfbc0250888cb9c670d421fd1bf5a152f34878e08edfde306b320857c73"],"ts":1793449913,"cid":"poa-mainnet-1","sig":"46pAjmBR4dDuoJazb1y1eZ6ry8mEznXRCncaX2CoxMMvXWyWZVTexUeakK1nhXG4RRoyUQwMb7SNSjifC1sjkzkm"},"checkpointed":{"height":244937,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:22:17.315Z","checkpoint_height":244937,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
