I came up with this in half a minute
you are a
chaincop
you may PM one person to track them.
You do not know anything until to PM the mod again, in which you get a post that gives a list of all people who have done an action or have an action done by this person in no particular order. You also get a list of roles that belong to the people in the group, but you do not know who is who. You win with the town.
