I have a plan for this. I know of an ad network that will let me run ads on Libr that supports both SFW and NSFW ads. When you sign up for Libr you have to say if your blog is NSFW or not. Then Libr flags all content you post as NSFW or SFW depending on what you choose. I can detect what content is on a page, then run SFW ads around SFW content and relevant NSFW ads around NSFW content. Google used to do the same thing if you turned off safe search with their AdWords ads. I'd run the SFW ads near NSFW if it were possible, but it's not.
