I predict Google will come around and open up your adwords account again. Don't give up on it if, of course, you want their traffic. Were you running product listing ads (PLAs) as well?
Not a single person from Google will ever read the e-mails from your Adwords account unless you bring in thousands of dollars of revenue for them every day.
I knew a person who used to spend $3000+ a day on Adwords who never got much attention from Google (reseller in the cosmetics niche). The only thing he mentioned is that at some point Google assigned him an Adwords account rep. He followed the advice of the account rep and got all the ads and keywords suggested by the rep banned. It would be funny if it wasn't so sad.
Eventually the person's main account was banned. Last I talked to him he was creating a bunch of fake accounts and running cloaked campaigns. It was much easier for him to be non-compliant on Adwords than compliant.
I can attest to this claim. Even with monthly budgets in the tens-of-thousands of dollars (maybe $20K on Google and $15K on MSN/Yahoo!) you barely get noticed.
The real issue (verging on comedic) is when they kill your keywords or ads, and then your volume drops to the level where they really ignore you thereby preventing you from getting the service you were (or wanted) prior.
Usually when a post about Google shows up on the HN front page, someone from Google shows up in the comments and takes some common-sense action. They are probably figuring out how to handle it now.
Trust me, as someone who's run very large advertising campaigns, having someone from Google read your email doesn't mean they'll do anything. They have ridiculous rules for larger advertisers, as well.
