We have had this situation: domain disabled, account open, no email. It took two months of attempts to contact Google, via personal contacts and other avenues, etc. The domain was earning $10,000+/mo (the only domain in the account). Eventually it got re-enabled. Fortunately, our revenue was already diversified since we have read about Google's sudden/unpredictable actions. Further reading: [news.ycombinator.com...] [news.ycombinator.com...]
If we did not diversify the revenue, our earnings would have been perhaps $45,000/mo with AdSense.
