The games.on.net general rules which apply on all servers can be found here:
Mount & Blade Server Rules
Specific Game Rules
Admins put time and effort into this community AS VOLUNTEERS. WE DO NOT GET PAID TO DO THIS. The last thing any of us want is for people to comment on how we're doing our jobs. Most admins have ZERO TOLERANCE policy on this issue. I'm not kidding, you will be permanently banned if you push the right buttons.
Team killing someone or intentionally getting in the way of a team mate so that they team hit you like standing in front of a friendly archer when he is trying to shoot the enemy.
Poll kick abuse
Vote kick is for a player who is a) breaking the rules or b) afk. There is NO other reason to poll kick a player.
Do NOT poll to remove bots if they aren't any.
Disrupting game play
Not taking part in the battle but instead playing hide and seek and running to map edge/ hiding in buildings or blocking your team on door ways, staircases, bridges etc
You should always make an attempt to join the loosing team where possible or switch when you can to assist them.
Glitching into places that were not intended to be accessed or used as part of the map or modifying your client OR running 3rd party software that causes an abnormal effect in the server.
Blank naming also falls under this and you will be banned if you do this. (new 19/08/2012)
Using an admins name or claiming to be one from gamesonnet will score you a permanent ban.
Breaking any of the rules listed will result in either a kick or a ban (note: ban lengths vary depending on the severity of the offense)
Bans are not discussed on the forums.
