I wouldn't be surprised if the advertising provider requires and checks for real whois info. If not, there's probably a business model in there somewhere.
Small advertising networks are notoriously lax. The ad network in the screenshot, pogads.com, has this testimonial on their front page:
"I've been banned from adsense for advertising online with companies offering popups, I registered with pogads as an adsense alternative and I see the real money potential in my service
Roger, IL"
It's positioned as the first testimonial of several.
