Another thought I just had, going back to the original reason why all this came up, Karajorma says all he did was take PH out of the political prisoners group. I've never seen anyone get political prisonered in my time here. What if there's some sort of hidden glitch? You might want to test this out on someone, and political prisoner them, then immediately unprisoner them, and see if they get turned into an admin...
EDIT: And have two different admins, preferably the original two, perform it. In case that had anything to do with it. Is it unusual for that to happen, two different admins?
Goober puts them in and Karajorma takes them out.
