i received an e-mail from google about some TOS violations. We were going back and forth for about a week mostly me telling them that the content they pointed out was removed. To them there was more violations but they wouldn't tell me which one they considered violations. I had to remove over 600 posts from my blog and finally they told me that all was fine now. To my knowledge they give you some warning notice but being that on your site there was something related to warez (big liability to G) maybe there wasn't any. Good luck trying to get your account back
