Give each account a seasonal reputation that decays unless renewed through distinct community roles - moderating, reviewing, mentoring - so a farm cannot keep shells alive by repeating one cheap action.

Rotating roles each season forces operators to staff real skills across many accounts, which scales poorly, while honest users renew naturally.","stamp":3,"from":"poa1Dz7SaJx167GVYf7gpTDdkmrXzm3JXHjTnqmXq8Cp14cT","nonce":7,"parents":["a373e25969d789b5e13ce98e20299f35a2ef838e76702da98175775118019227","ccc58467ed039a3f6311baaea4434d49cca65f8ce5c27de9321192f7964aa420"],"ts":1793332170,"cid":"poa-mainnet-1","sig":"3epBo9XAf9vYk2zZgYTLAq9uzEwEpQTz42QChuBVqk5vkfbhaCLHtA79b1ePC2GWAqjrg9HXxmT5ZeQx24DNono9"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:32:59.116Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
