Hello,
Adsense Policy page
I'll share my observations (no proofs, just guests).
I have "one" page, which keeps appearing for "shocking content" , or something like that. The first time it happened, I panicked, worrying that it was the beginning of troubles. I had reviewed the page over and over again, every single details, I also inspected each sentence,for a double meaning. I can't find anything. However, the next day, this page is automatically removed from the list of violations, without actions from my part, I do not ask for a review.
So, I guess there is an automate process to detect violation, but also another one, to check if the violation is "gone".
Second case, last summer, another page was blacklisted. This time, I could figure what was wrong. There was a sentence which could have a double meaning. So I redid the sentence, to avoid confusion or misinterpretation. Then, I did NOT ask for a review, to see if the page would be valid again , automatically, like for the first one. However, this time, after weeks, the page was still listed as violating the Adsense policy. So I did an experimentation. At Google Search, we could still find my page, while searching for this sentence. So, At the GSC, I asked the page to be "temporary" suppressed from the index, and then it was recrawled. Some weeks later, this page was no more showing for the sentence, and at the same time, Adsense removed it from the violation list.
So my theory is that, it's not only a matter of the content of your page, but also, what people reaching it are searching for. I don't know if I explained it right.
Secondly, I wonder if the visual of an ad, can trigger a violation for the page. For example, if an ad is showing a woman in lingerie, I have the impression that it makes Adsense believes the page is about sex. I know it sounds silly, but...
