Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello, I made an account yesterday 9/26/15 got to level 6 and logged out in Goldshire. I tried to log on today but kept receiving an "unable to connect" msg... after an hour and many more attempts I received this msg : The World of Warcraft account has been closed and is no longer available for use. Please go to http://www.wow-europe.com/en/misc/banned.html for further information. Anyhow I have no clue as to why this would occur, I don't bot or buy gold or share any of my personal information so there is no reason for my account to be banned. I didn't use any vulgar language or speak to anyone really in the total 3 hours i spent online. I have made a new account to play in the meantime but would like to get to the bottom of this so that it doesn't happen again. Thank you for your help.

The "Unable to Connect" is due to an incorrect input of your password.

The account no longer available part is an auto-temp lockout Nos has. After some time you can input your password correctly and login.
