It's becoming pretty apparent that regulation is necessary in the advertising space. Left to their own devices the biggest, most well-funded ad companies are doing little to combat scams, misinformation, and outright fraud.

There's denial of responsibility at every level. What's funny is that Facebook has absolutely taken on the responsibility of censoring content - blocking nudity and certain other topics. But at the same time has denied responsibility for misleading or fraudulent ad content that gets on its site. I think the difference is that one is cheap to do (object classification via machine learning) and the other would require some real manpower.
