Today, first time I logged-in to math.stackexhange.com. I have other associated accounts also, so I got $101$ reputation initially. I vote-up one question then suddenly I undo the vote-up. After that it shows me supporter badge on my profile. If I am going to all accounts page, the page shows one bronze badge for mathematics account. Isn't it a bug or regular behaviour?

• When I made my first down-vote, I removed it within a few seconds, but still got my Critic badge. It seems that the badge triggers don't have an untrigger mechanism. Jun 8, 2012 at 12:20
