Nostalrius Begins - Quality wow vanilla realm (1.12)

I was away for some time and hadn't log in the game. Yesterday night i tried to log in from the laptop but forgot to disable addons and all popped in my screen. So then I logged out to disable them and log in again . When I tried to login back into the game a message appeared saying that the account is banned?

I have two characters on Horde side on pve server Deathseed is the name of 1 of the characters and account name is Stinki. Is there any way you can help me?

Thank you in advance.
