You say "visiting a site" should be enough to "enter into an agreement" with a site to agree to view their ads.
Surely the same should extend to the site, such that "visiting a site" is enough to "enter into an agreement" with the visitor to agree to show only ads that are relevant, non-intrusive, and do not contain malware.
The main short-term incentive for ad networks is to show more ads, make them more intrusive, and sell them to whomever pays the most. It's simply not in the long-term interests of a website, or a website visitor, to be part of an ad network.
