locked/banned account?

Dear Gamemaster
When I after a week's stay in hospital, wanted Login to Nostalrius again. Was informed me that my account has been closed. Could you please tell me why this happened, and what can I do to make this undone?
My character name is Nickname
I bought neither gold nor I had ever used a bot.
Thanks for the answer
Greeting Nickname
