#2 is patently false and the biggest reason I don't try to train people not to use Google as their URL bar. It is not cool when a tween kid tries to visit the Poly Pocket web site and finds something very different.

Raise your kids like you want, but I would argue that the potential positive gain to be had from telling your daughter that you trust her to be responsible and come to you if she has problems is far far far greater than the: [probability that she will randomly run into that while she is still 'too young'] multiplied by [whatever harm that could conceivably cause].
I know protective parenting is all the rage, but think about it rationally.
I don't even know how to respond. It is not a fabricated concern because it happened to my kids' babysitter in my house.
Having experience with what happens when a kid goes down a pornography rabbit hole, the worst that can happen is a screwed up life. Will seeing porn guarantee a screwed up kid? Of course not. Does porn have the ability to screw a kid up? Yes.
I'll take a few steps to keep my kids and those who come to my house safe so I have the opportunity to provide a foundation so when they come across it, they aren't screwed up by it.
There could be young children who have access to that computer or that network.
