Miscellaneous
As TWC wiki points out, a common misconception is that using spies/assassins will lower your reputation. Using spies lowers your relations with other factions, but does not directly affect reputation. Using assassins, as long as you don't get caught, has no effect on reputation, but if you get caught and you're not at war, a captured assassin from a failed assassination attempt will cause war which does affect reputation (-0.00125). The Chivalry or Dread of your Faction leader also has no direct bearing on reputation (though his actions that made him Chivalrous or Dreadful can, depending on what they were).
