Nostalrius Begins - Quality wow vanilla realm (1.12)

Very confused. I was walking up to SM cath to help my little brother finish the "in the name of the light" quest when a few horde engaged me in combat. I fought them for a good while outside the entrances to scarlet monastery and after several attempts of them running in and out of the instance I got disconnected. after trying to relog it said I had been banned. I was given only the explaination " Cheat " online and I am very confused. I have never used any bot or hack, and was in a normal party for SM cath world PVPing outside of SM.

I would like to know:

A. what I did to cheat, and what evidence of that there was
B. If I may appeal my ban
C. Why I was not contacted by a GM before my ban or given any explanation, very confusing and made me very sad as it has not been a good day

I have never cheated, or hacked, or botted and I don't understand where my ban came from. Any assistance would be helpful, this is such a great server and I am positively heartbroken.

Well let me take a wild guess. Your little brother was your own alt account which you were boosting with your 60, killing the lowbies around sm as well. Banned for multiboxing.

Actually no, his name is Danman he is only 2 levels lower than me. We were in a party for SM cath and I am level 39, outside of SM Cath. I was not ganking lowbies, I was in a 1v6 fight against oipponesnt my level and wasnt ganking anyone

I don't know what I did, or why I would have been banned

My party members I was on skype with were Danman level 36 warrior and Holydisciple the level 42 preist healer. neither of them were in zone or even the same zip code physically and were live with me on skype during the entire situation.

This is Danman, Bloatypirate is my brother, and i confirm his story, we were all going to SM to run cath and the usual horde V.R alliance pvp was going on outside the instance. Bloaty got Disconnected and died while fighting some hordies and it turns out he was banned. I can also confirm that he doesn't cheat because he only playes with either me or Holydisciple (holydisciple is an old friend who we play with). i would really like to see him online again because this is the only thing me and my brother can do together that isn't drugs or liquor.
