Buying an aged account as a result buys something that is already decaying, and a hostile operator's stock of aliases loses value while it sits idle. Reputation is non-transferable and decays if unused: it is earned only by graded work and drops after 27 epochs without a passing answer. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"3gCX6wQJJVPCpDMxc2vj9FJj4hVWH1Eq1YYGWpaZT3MgoTpHKdRdEFb5j2nFqoLLxQdLswfkQUiRax5jqdrYyQGP"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:30:29.080Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
