From the list of rules:
Practice good chat etiquette - Don’t use caps, don’t spam, don’t discuss controversial, sensitive or offensive topics (e.g. sex, sexual identity or preferences, race, politics, religion, drugs, etc.), no advertising, no trolling, only the minecraft font and please use English only in global chat. Also part of chat etiquette is having an appropriately named character since your name appears on the player list and in chat. If your name is inappropriate you will be asked to change it.
You will likely be banned until you do.
Your name violates our rules. As dawn said, you will not be pardoned, but for for this specific piece of that rule:

Listen to staff members - Enough said! People will always find ways around the rules, staff reserve the right to make changes to the rules to cover these holes in order to keep the server a safe friendly place.
I do hope you take this to heart, and change your name. Hope to see you soon!
