Why i got banned ? Soad22

[soad22]

Hello , i got banned some months ago , but i really don't know why , i didn't log for 1 month , and when i wanted to play a little bit on the server , at the login , it just appeared ,, Your account has been closed and is no more loger to use ''. Uhm , why ? I've never cheated on the server , never insulted GMs and players , and there would be no reason for getting banned , can you give me an information why i got banned so ?
