Isn't the question of why the account was locked just as pertinent as how?

What would be racing through my mind was my account hacked, as if so maybe other services I use be hacked.

Or did I possibly break the terms of service? If so, what may have been the justified reasons for me doing so, or Google's reason for preventing me so?

That's where full communication with Google would be so essential to remove the ambiguity and resolve what may be a bigger question at hand.
