Tinder is in trouble. And for that matter most dating websites. It is not that hard to go to Tinder and find profiles of people asking for money, which under this law makes Tinder liable.
Tumblr should also be under a ton of scrutiny.
I'm also wondering if camgirl sites are freaking out. As sex shows are not technically illegal, all it takes is one bad apple and the whole thing comes caving in.
And yea, Backpage and Craigslist were actively working with victim's groups, NCMEC and law enforcement to go after pedophiles, sex traffickers and other bad actors before the Goody Brigade went for votes.
