Couldn't agree more with the sentiment here. It always blows my mind when I come across what appears to be a terribly designed (and outdated) squeeze page that still goes gangbusters on conversions and avg rev per sale
I have had a similar experience of AdSense from Hell, thank GOD it is not my source of income or it would be very bad. But essentially AdSense was unable to access my website early on and decided to set the account to 'INACTIVE' after repeated attempts (upwards of 10) to reach out to AdSense support and having groups of people tweet at them (no response. ever.) They are still completely quiet and the 'return to AdSense home' link only persists to reload EXACTLY the same 'INACTIVE' message - perhaps the worst user experience on the internet. It has even gone so far as I have had a Google API Billing specialist whom I was coordinating with for some API stuff reach out to AdSense on my behalf after learning the details of my case, and even he said there is no hope...
We are relying entirely on engagement analytics at this point, focused mostly on social media and organic search - and then facilitating outreach to get feedback from users.
