okay I know G will say no if we have adult stuff and adsense on the same page but how if we got traffic from adult site, but no actuall adult stuff on our site r they allow this?
Well, their only concerned is that the Adsense cannot be on the pages which contains Adult contents so what you are doing is okay because in theory, you have no control over who visits your site and who links to your site. I run a Directory site and I use Adsense on the site, however I do have an Adult Listing section and for those pages, Adsense are turned off. I've consulted Google and they told me that it is okay.
you are not allowed to use any kind of adult (hits from adult or adult material on your site) you can also look http://forums.digitalpoint.com/showthread.php?t=328337 . it's a similar discussion
