Basically, don't be a jerk.

Context-appropriate cursing is allowed (as long as you aren't being a jerk, see above).

Cheating is being a jerk to other players (see first rule).

Having someone disagree with you is not them being a jerk.
Claiming everything you don't like is offensive makes you a jerk.

If someone marked as staff says you're being a jerk, you probably are, and arguing won't help.

Additionally, each Minecraft server or forum section may have extra guidelines. Please take a moment to look over information related to each specific area you're interested in.


tl;dr Citrine Realm is for mature players, not people that need hand holding to acting appropriate in groups.
