While reviewing your account, we noticed that you are currently displaying Google ads in a manner that is not compliant with our policies. For instance, we found violations of AdSense policies. [...] As stated in our program policies, AdSense publishers are not permitted to place Google ads on pages with adult or mature content. As a result, we have disabled ad serving to the site. [...]What they refer to is a collection of posts I had labeled "porno". Not that those blogposts were pornographic in content (you know me better than that) but the Google man didn't check on that. The mere mention of the word porno seems to trigger an automated alert at Google HQ that this is a blog for adults with adult content. That sort of gormless automated alert generation is very much the essence of Google (from news items to best buys to advert placements) they built their business empire on. Good on them for raking in the cash that way but a little more human input into weeding out clearly faulty or nonsensical "alerts" would go a long way.
I wrote to them about their mistake but as long as they don't see sense you won't see any adverts here.
