There is a big chance that your site will get pr banned and will not be indexed. And that will hurt much bacause google has the biggest search share.
yeah, i guess you could. But you will suffer on SERPs as they penalize keywords like sex, sexy, porn, nude and the like
No, not only nude picture but no adult content. It is very risky, adsense can ban you anytime based on their judgement
Read the Google Adsense help pages instead of guessing! Content on sites with Adsense have to be "family freindly", so definitely no sex-related or "adult" content. https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=105957
If you uncheck the sexual content option ur application cannot be submitted....hence no porn or nudity allowd
no, adsense can't allow the adult contents. if you add adult contents later on, then they must disable to your account and all of ur earning will damn. so don't try this.
