All that you need to do is listed there (for MA).
Edit: But seriously.
Anytime you do anything in the MA for the first time you get a badge. All the defeat X, Click Y etc.. all but the first one is gone.

I noticed after logging in today I had lost a lot of MA badges but gained a few as well could anyone point me in the direction of a list of available MA badges and how to get them. I think the list on Badgehunter might now be out of date
