Use your common sense. All of the rules are up to the discretion of the server staff except for what is written. Some rules may be situational. Don't be a shitter or try to avoid punishment.
Teaming is allowed as long as it isn't causing the round to be delayed.
Delaying the round intentionally will get you slain. Examples of this are:
Staying in the Warhead room for minutes on end.
Not leaving the surface area for no reason.
Mic-spamming is not allowed.
Playing music is allowed, as long as you aren't being obnoxious with it.
If you're asked to stop by anyone, stop doing it.
Exploits are forbidden and you will be punished if you use them. If it was clearly not intended, then it's an exploit.
