Nostalrius Begins - Quality wow vanilla realm (1.12)

I played on my account yesterday and when i tried to log in later on i was banned. I logged onto the home page and it says "You are banned until August 16th 2015 17:52:10 PM for the following reason: "Compromised account"." What does that even mean? That someone tried to hack my account or something?
Anyhow my character on the account is called Tchami and is a recently lvled upp 60 rogue. If someone could help me sort out this problem so i can keep playing on this very impressive server i would appreciate it.

Best Regards Tchami
