Ban - Appeal

Hi Team,
First of all, I would like to thank you guys for what you are doing. I haven't had so much fun playing WoW in literally years!
Now to the topic at hand - An account of ours got banned yesterday - Character Name: "Minerbankero"
Ever since we started playing here, we've been playing together with a friend of mine - JohnyT. We are leveling together, sharing loot, gold and anything in between that we may need.
As we are still new players and our inventory got a bit full, we created a third account that would host our "bank" character (the above mentioned, now banned, "Minerbankero"). Like I said, we share everything and that included our 3rd account used as a bank.
We were both using Minerbankero to trade, store items and even check the AH while we are questing/in a dungeon.
Last night, my friend realized our bank account has been banned. Now, there weren't many things that are valuable in the character. If you guys can unban him, that's cool. If not, we understand as well.
The thing that is more important to us, is to understand what rule have we broken, in order to avoid any similar problems in the future.
If you can provide a link or a thread that banking characters are being discussed, we would immensely appreciate that!
In advance, thank you for looking into this
Kind Regards,
Anton
