The name of this thread is rather misleading. As you even state yourself in your thread, there is no special rule enforcement for naming on RP servers. They don't police names that are "out-of-context", only names which are inappropriate according to the Terms of Service.
I can understand WHY you feel this way, but I don't understand why you feel they aren't doing their jobs. It's right there in the server description before you even login. I wouldn't, but I could make a "Darth Susan" and "Jedi Billy" right now and it'd be completely legit.
I'm just asking for the usual existing naming policy as stated in this link
