But a wiki's admins have to work in line with the TOU. They can set their own standards, but they're still bound to the basic rules. While this matter can definitely be taken to staff, I suggest going to the normal hierarchy first.

If you have issues with certain users' language, let them know on their message wall, and explain why you think they should stop. If they refuse, ask the local admins. If they too refuse to address the issue, then take it further.
