Not only do the admins ban for such reasons, they also never include new players for a while. I guess its rare to see new players immerse themselves with the admins. I'm not saying its constant though.
I agree with the ban somewhat, a permanent ban is a little bit too much. A name like "Isaac Clark" should be fine whilst "Master Chief," I personally would ban if I saw Master Chief. No, actually, from hosting experience, I always give users a stuffton of time to fix themselves. Then all my friends/admins start asking to ban him because I keep him there. My admins never ban unless I say they can. :l
Bottom line is:
This ban was wrong and should be lifted for another chance.
