Nostalrius Begins - Quality wow vanilla realm (1.12)

I haven't even played the toons on it in weeks so confused as to what possibly reason it is banned for.

EDIT:

I want to provide some more information that could probably help the GMs investigate this.

A month or 2 ago I used my 60 undead mage on a different account from the banned one to trade gold to the Night Elf Rogue on the banned account via the neutral AH in Booty Bay. I then traded that gold to a 3rd account I have which has a 20's night elf Hunter. I can see why this would have created some confusion with whatever algorithms you guys use to detect trafficers but if you see the logs you can be able to tell they are all from the same IP address and nothing violating the TOS was done with them as far as I am aware of. I hope this extra information can help.

my account got banned aswell, just like that...

The mage was Aøe and the hunter is Zintos


I don't understand why I would get banned if they're all under the same IP. So it's now not safe to trade items/gold cross faction for fear of your algorithms banning?
