Google Adsense in some Adult Sites?

seriously i know very clear adsense dont allow adult content site but if your site is a mix type not a pure adult you might be able to get into adsense this what happen when i browsing a music forum with a adult section having adsense ad i wonder is there anyone earn money thru adsense by your adult site and how you all approve
