IFrames, can ad companies detect it?

My question has to do with iframes and showing ads on prohibited adult sites.
What happens if you sign up for an ad company for a site that’s approved, but then you show your ads on a non-approved (and prohibited adult) website?
I know that if you just showed your javascript or iframe code in that adult site that you’ll get busted. But what if you call on an iframe and in that iframe is a link to your approved website which then shows the ad?
Is there anyway for them to track it? I assume they’ll just see it’s coming from your approved site since the iframe is calling on it. Anyone with experience with this?
