If you search in Google you will find a lot of sites monetizing sexual content with AdSense. The ads they get are extremely targeted as well. So is it OK to use AdSense on sites with content like: REMOVED There are a few dozens of sites with such content ranking high in Google and runing AdSense. Don't tell me Google didn't notice that. Anyone?
If you have a site like those i would probably contact google BEFORE putting adsense on it... Better be safe than sorry dude...
If you can't view the content to your boss, your kids and your family, then chances are it is not allowed. Peace,
I got an infraction for the two pics and they are published on sites running AdSense. Go figure it out I'm not going to use AdSense on such sites, just in case. Too much risk.
