Medals go away when they get a forum ban. (sometimes they come back, though, so some older banned accounts might have their medals back)

Portrait goes away when the game account is banned. (maybe also if the character is deleted by the user?)

I can say this isn't a proven fact. My friend has a permanent forum ban but still has their medals. It's merely been an odd coincidence so far though.
