We operate a mature server, and regardless of what age group you personally think Minecraft is aimed at and regardless of what age group you belong to we expect you to behave in line with that maturity, as such we will not be banning words that are considered profanity. However, continuous flaming of another player, using profanity or not, is not allowed and should be handled with normal warn-kick-ban.
Recognize that this does NOT mean that you can come on the server and start spamming profanity. Chat spam is a form of grief.
