A few years ago, Google said, "oh, don't worry about removing ads on violating pages. We'll recognize it and restrict ads for you."
Yesterday, I got a warning that I was at risk of losing my account entirely because of alleged "violations"! There was nothing under "Must Fix", but I had about 30,000 ad requests denied.
Why? The claim was "sexual content", but the pages had nothing sexual about them! One was a classified ad for a woman looking to clean houses!
I'm just at a loss. My CPC is down 64%, and I can only guess that I'm being punished for content that Google has decided it doesn't like. My business is quickly becoming an expensive hobby, but after 20 years I have no idea how else to make money.
