From my perspective as a user, it doesn't matter. If the ad networks and their customers are unable to enforce standards on their advertisers, then I have no choice but to block them. Making it my responsibility is not an option. Its not possible to enforce compliance with some sort of ethical standards industry-wide, but it is possible to at least encourage it, especially if you are a large player like Facebook or Google. From my perspective, they don't even appear to be trying. > I guess you could argue that Google and Facebook controlled enough of the market that if they acted in concert, they could have prevented the current situation, but they certainly would have faced strident accusations from advertisers of anti-competitive behavior and would have attracted the interest of regulators. (And if that is your argument, you should say so.) Its not clear to me that this is the case. Simply enforcing standards on ads is not the same as limiting competition. Its an issue of a corporation deciding to not carry your content because it does not pass some presumably published and neutral guidelines. At the very least, it is not as clear-cut as you are making it sound.
