Q: X word is in the Curse filter, but Y word is not. Why is this?

A: Our filters are created mostly from requests from parents and/or large groups of players. We cannot nor will we attempt to add every possible offensive word to the curse filter. Filters are created at our sole discretion and we will not add words that we do not believe are necessary. Since you can turn the filter on and off, we tend to make the optional filter on the stricter side. A few words that are considered widely unacceptable are also put on the permanent filter but for the most part we try to leave "curse" words on the optional one. Threatning staff or purposely coming up with "work arounds" to the filter when it is (mostly) optional is not acceptable.
