Gmail account disabled

My g-mail has been disabled. I have no idea why. I have gone over the terms and services and feel that I did not violate any of it. There seems to be no one to contact regarding this. If I want to ask on a forum, I need an account to do so. It's very frustrating. No one can seem to answer the simple question as to why. How can I prevent making the same mistake in the future? Please help me to figure out what went wrong. The email is ***@***. Thank you.
