I have been using Adsense for around 18 to 20 years, with no problems or questionable tactics. My latest project is hitting the "The team has reviewed it, but unfortunately your site isn’t ready to show ads at this time. There are some issues which need fixing before your site is ready to show ads." and from experience I have worked my way through whatever the Google Adsense team think I need to fix. This time - it appears to be a dead end for me as all they give you is links to video / web pages to help you identify the "problem". One one of the pages it says they reject 96% of all website applying - so don't take it personally!
I realise this must come up a lot, however for people who have been Adsense publishers for probably longer than the age of the team members that are saying the website does not meet Google's guidelines, surely they could just simply tell you what the problem is. If they are saying the website does not meet quality guidelines - well they just need to look at the F****n mess their auto adds cause on a website - it destroys any user experience possible (in my opinion). I immediately leave a website with Google Adsense plastered over all of the website - by auto adds.
Well that got it off my chest, and nobody at Google will care less.
