Then please get that added, because it's rather bad the way it is now.
A rules section is something that's supposed to be trustworthy and reliable, who or what are people to trust or believe in on a site when they can't trust what's written there like now?
So yes go and get everything added, and if for some reason you can't, then stop moderating people that followed the written rules.
I just dislike unfairness, which taking action against people for things that doesn't go against the official rules definitely is.
(How are they supposed to know of 'hidden rules' that could just aswell be the whims of the moderator with how they don't match the rules section?)
Just see to it that your moderating actions and the written rules align, I frankly don't care which is changed to fit the other or if you change both, just see to it they align.
(Means far less room for anyone to complain or argue against what you do, so would be in your interest to do something about it I believe.)
