Great idea in the short term, probably unworkable in the long term with how easy it is to spin up new keys - 1/2/3 years from now accounts created in the past could be switched over to spoof newer entrants so only really works for existing Nostriches

Good point indeed. With the Nostur client it shows a "previously known as" once a user changes their name. Would be nice if there was a historical record stored on relays that could be inspected at a later date. Might help with poaching older keypairs for spoofing dates, if it can be seen that the name change came afterwards.
