I agree, but the complete lack of transparency on Google's part is still disturbing. I understand that customer service isn't Google's strong spot and that there may even be valid reasons for being a bit opaque when combating black hat SEO, but there's no excuse for not telling you what you're alleged to have done in the termination email.

And there needs to be a better appeals process than the current system of "find someone who works at Google to escalate your issue for you."
