[Research on](http://www.cato.org/research-briefs-economic-policy/can-online-activity-be-regulated-evidence-adult-websites&source=gmail&ust=1789584039213000&usg=AOvVaw0ujI0s7891qiYGf-ls4Snd) banning minors from adult websites suggests the latter. The researchers looked at

Pornhub use fell by 54 percent, meaning nearly half of prior use remained after the shutdown.
