So yeah, it was tongue in cheek, with a side of reductio.
I'm not saying if Sally starts a forum and it gets hacked and someone posts illegal stuff she should be fined or charged with anything. I'm not saying she should even be in trouble if she gives one person who turns out to be a jerkass posting rights and that person posts illegal stuff. But if she opens up public signups, gets a billion or two users, then says "well I guess I'll just have to pay a bunch of people money to look at all this gore porn that's getting posted" the rest of us should go "uh, no, you should instead just stop".
[EDIT] and given that second sentence, no, I'd get nowhere in American politics.
