Sorry ... I can GUARANTEE YOU that site would be shut down in days, by whomever you contracted with for either web space or bandwidth, as soon as Pedophilia promoters started posting their stuff. And that would be done precisely because you violated someone else’s CONTROLS on the Internet ... LOL ...
We don’t even have to invoke Pedophilia ... we can just be talking about someone posting a favorite movie of theirs or a song that they like. Pirate Bay comes to mind here ... :-) ...
You’ll either CONTROL IT whether you like it or not ... OR ... someone else will CONTROL YOU (law enforcement, lawsuit, courts, etc.).
But we don’t even have to talk about copyright violations either, we can just talk about not liking Obama, to the point where people start posting threatening remarks and also encouraging violence against him ... You’ll either delete those or else your site will be shut down whether you like it or not.
SO NO ... you WILL CONTROL IT or you’ll be taken offline!
