I was logged in to 3 characters at once, I am not disputing that. I am aware that having more than 2 characters on a MAP out in the world is not allowed, however it is allowed in capitol cities. The thing is, I was not out in a world map, I was inside a dungeon which is located in a capitol city. The rules (as stated below) are unclear on this, and I honestly did not realize what I did was wrong:
"It is forbidden to multibox more than 2 accounts (2 characters) within the same map zone (Elwynn Forest, Wetlands, Mulgore, The Barrens are all examples of map zones). There are no limits on account/character count in Capital Cities."
I was inside a dungeon, inside a capitol city, not on any map zone as listed in the examples in the rules. The multiboxing rules simply make no mention of dungeons. I sincerely apologize, I didn't realize I was in violation, or I wouldn't have done it. I would like to appeal the ban on this account. I promise to not do this in the future now that I have been made aware. I would also suggest perhaps making this a little more clear in the rules, so others are aware as well. Thank you for your time and consideration.
