Maybe I just don't fully understand the bill...but how is this not an open and shut violation of the first amendment? Not in the usual "i can say what i want and nobody can stop me" kind of way, but in the "government cannot directly censor its citizens" kind of way. Particularly with the inclusion of automated filtering, it sounds like the government mandating that all internet companies disallow anyone from posting content matching a set of parameters. The target (sex trafficking content) doesn't matter, the important thing here is that its sweeping government mandated censorship, with legal ramifications. Am I missing something that makes this constitutionally allowable?
