Here are two peculiar badges that have never been earned:
Question is, why is there a gold badge, at this slightly-advanced stage, with double the requirement of a silver badge that for all intents and purposes, would be a lofty and improbable gold badge in difficulty?
The concern is: the increasing population may counter the increasing efforts of senior users, as more users means more votes, countering likelihood of 'zero-score accepteds'.
There is a fair chance that someone could ever earn a 'Tenacious', but... Unsung Hero- can't see it.
Should Tenacious be elevated to gold, and Unsung removed?
