Expecting draconian regulations on social media to work is a recipe for failure. How many billions wasted on the war on drugs? People are always going to want to view extremist content, see beautiful people that cause body image issues, etc.
If people didn't want to see it, they wouldn't click on it. Banning it or regulating it is not going to change that, it's just going to cause it to shift elsewhere. It's human nature.
