Banned standing in town selling items

Hello there Nostalrius Gm's.
I don't understand why im here on the forums now trying to get back an account that just got banned, when I was posting and selling items in Stormwind.
Is this an intended ban? Can you please explain what did I did wrong. The only thing I can come up with is that I added the item I was selling to a macro to post it. Don't think i deserve a permanent ban for that.
It was on a bank character namned: Mailmeoffers (around 01:15, server time)
Best regards Adanimal
