Nostalrius Begins - Quality wow vanilla realm (1.12)

Me and my friend were discussing classic wow and i had told him about this server and i was showing him around (using Skypes screen share) and he asked does the server have the warcraft 3 easter egg in the throne room of the Undercity so i made a undead warrior named Billiejoee and began to run to the Undercity. When i had got there i ran into a tauren warrior waved at him then continued to the throne room where i dc'ed. I tried logging back in but it said i was banned. I immidately went to see if there was a reason but all that it said was i had a perma ban without any specific reason. So i made a new account, I have obeyed the rules of the server. I had thought maybe it was the name but the name was not violating any rule i had seen. So my question is why was my account --snipped-- banned?
