I'd rather unban everything, legalize everything and instead have people take an aptitude test to determine how well they can deal with all aspects of the internet. There should probably be grade school and high school classes to harden people against all facets of unstable people. An Internet version of the Agoge [1].

If a student does not pass the class they are sent to an advanced training camp to fix their nutrition, get them off all prescription drugs and teach them how to verbally joust with the master trolls.
