Update the Rules.

Personally, I don't think there are enough rules, as people always end up breaking or bending rules, or doing something completely out of order, and there's nothing in the rules about it. Here's a few rules I think should be added, feel free to leave ideas here aswell.
1. GOD ARMOUR, SWORDS AND BOWS ARE ONLY TO BE USED BY ADMINS & OPS.
2.THERE IS TO BE ABSOLUTELY NO BUILDS WITH A SEXUAL, OFFENSIVE OR RELIGIOUS INTENT
3. VULGAR LANGUAGE IN UNACCEPTABLE, SWEARING WILL RESULT IN A 5 MINUTE MUTE
4.ASKING A SERVER RANK FOR ITEMS WILL RESULT IN A 5 MINUTE MUTE.

Well i agree with everything but the god stuff. If they manage to get god stuff in survival, cudos to them in my opinion.

Well everything what you said is in the rules.

Just that it isn't written to not build any sexual or religion offending builds.It says not to behave like that.

Pretty much you can use those rules.

I'm not sure about the God armour.
