Out of curiosity...which one of the publisher networks allow you to participate if your blog has lots of curse words within the text's content? (I'm sure Adsense wouldn't).
I know AdSense don't allow adult material, but would some curse here and there really cause them to pull your account?
Most CPA or affiliate networks would probably be fine with it. I can't say for sure, but... I bet if you just email your preferred network and ask what they think of profanity, they'll let you know. (Or you can just read their terms.) Maybe Adult Friend Finder ads
Adult Friend Finder routinely screw the industry by allowing their ads to be displayed on sites using stolen content. They also had their hands way deep in the Zango cookie jar. Check out http://www.zangoblacklist.com for a list.
