What are the community rules?
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.
