I remember this script from the Bluzone. It autobans you for fifteen minutes if you use the <> characters in the name.
I always was of the opinion that it should tell you to /setname FIRST LAST MIDDLE
And then autofilter for anyone who put their name in as all caps.
But yeah, this isn't the admins there.
Also, I think there might be a section to autoban you if you set part of your name to your username, but I dunno. Whatever this was, it was an autoban, not a badmin.
