Porn is almost as unavoidable as ads, especially for kids. We know the average age of a boy viewing porn is 11 (1)and that virtually all of them will see porn by 15(2). Of porn viewing done by minors 22% are done by children under 10 (3). Porn has also been proven to have significantly more impact over your brain than advertising. The dopamine response to seeing porn is similar to crack (4). You can't get addicted to ads. Pornography is categorically more dangerous to society than ads, tracking, and privacy invasions.
