I got the 'Critic' badge on my first down vote on a post.
But, soon I recognized that it was not appropriate to give a down vote for that post and revoked the same. And there is no down vote present from me all over the system at the moment.
But my user id is still decorated with the 'Critic' badge though I am not eligible as of the moment for the same.
Please have thought on this whether it is proper behavior or not?
