In a world where no one follows this policy, it is a Kaldor-Hicks improvement that gives you the majority of the gains, a very small percent of the people you contact a smaller gain, and the vast majority of the people you bother a small loss. In the actual world where a lot of people follow this policy, it is not even a Kaldor-Hicks improvement. It is just shifting value from people with filters to those without, with transmission costs along the way. The proper response is to make “the worst that can happen” a whole lot worse so people stop saying, “I might as well try pushing negative externalities on others and destroying value in the world.”
