Help: AdSense bot misdiagnosed my traffic, no way to contact Google

My website has a community of 500,000 users (all opted in), and I wanted to test AdSense as a monetization strategy. I registered, put up ads, and a week or so later I sent out an email to my list and had ~50,000 visitors to the page. $X,XXX revenue later, Google locked the account for "invalid traffic". I'm 99% sure the cause of this problem is that I went from 0-50,000 visitors in 24 hours (because I sent an email to my list) but there's no human in this review process. Is there someone here at Google I can reach out to and explain the situation in more detail? It's been nearly 2 months (the review was supposed to take 1 month maximum) and the account is still limited. Thanks!
