Why is my account banned?

Soooooooo i came back to my apartment after being home during holidays and tried to log in to check my priest and play some pvp.
At first i couldnt log in and i was getting "unable to connect" error and after few more times i got "account has been baned".
I was offline for more than 10 days i guess, never did anything bad to server, i was just playing pvp for fun.
My priest name is - Fateless
Can i get some explanation
