Hmm... and what about Government Rules:
Be open to criticism and never believe you know everything
This goes especially for people using the Protest option. It is there for a reason, you know?
The other aspect is that of unit settings, designations, battle strategy, etc. While you may want everyone set on defensive, remember that there are unit slants. A player may have a good reason to not set his unit the way you prefer. Check if he knows something you don't. Of course, he may just be stupid, but err on the side of caution.
And then I got ban for:
"for causing trouble by being an open critic and insulting the nobles"
My charracter never used any insultive word - by "insulting nobles" he refere on:
- My charracter publicaly warned King and General that they are doing premature attack
- After the attack failed they started blaiming players for not moving threatening some (what is violation of IR) and when my charracter pointed that they are responsible for failure they tuck it as "insulting nobles" and baned my charracter and his entire family from the realm
