This adsense behavior isn't even new- they did this to me in 2005! My website had a trickle of ads, just enough to pay for my college books each year. When I went to cash out Google decided it was click fraud and stole my money, with absolutely no recourse.

They're an awful company with horrible customer support. It's frustrating too, because my startup has investors who keep trying to get us to switch to GCP, but I don't think any responsible company would ever make themselves dependent on Google.
