World of Warcraft Naming Policy

Blizzard has posted their official rules for character naming in World of Warcraft, which essentially provides you with plenty of freedom as long as you use common sense. A snippet:
One of the first adventures you will embark upon within World of Warcraft will be that of choosing a character name. While your subsequent exploits should prove infinitely more exhilarating, great care should be given to name selection. The first impression other players have of you will be based on your character's name, so it's best to start off on the right foot. While choosing the perfect name for your character is left to your discretion, we have determined that some types of names are not allowed in this game.

Below are guidelines to help you determine whether or not the name you have chosen is appropriate for your character, guild, or pet. Hopefully, we encompass all manner of offensive names; however there may be inappropriate names which do not fit into any of these categories. In addition, the GM staff will only change a character's name if it is indeed found inappropriate we will not change character names for any other reason. We reserve the right to evaluate each incident on a case-by-case basis and in extreme cases, take action not detailed here.
