This seems like a really hard problem to tackle. The article kind of nails the problem in that none of what the children are doing on the videos actually violates any rules nor would it be classified as sexual in any way. There's no nudity, they aren't doing anything sexual, they aren't even truly saying anything sexual.<p>In a way this is the flip side of the "it isn't porn, it's art" argument. Not all nudity is porn, and not all porn involves nudity or sex. Trying to figure out where to draw the line is very much non-trivial, and is made even more so by the fact that exactly where that line falls varies quite wildly from person to person. As someone with no attraction to either of the fetishes (or is it three fetishes, are we counting pedophilia as one of them in this case?) mentioned in the article or as the focus of the videos I'd be hard pressed to classify any of the videos they're talking about as pornographic or erotic, but apparently there's a subset of the population that that isn't true of. Aside from banning <i></i>any<i></i> interaction between adults and someone under age I'm not sure it's going to be possible to prevent something like this from happening.<p>There's also the question of if we <i></i>should<i></i> be trying to prevent something like this. I know everyone's gut reaction is "BUT THINK OF THE CHILDREN!!!" and "OMG! PEDOPHILES!!!", but honestly if the children aren't being creeped out or feeling intimidated and threatened, aren't being stalked, and aren't doing anything sexual, how much effort should we be wasting worrying about some weirdo getting turned on by someone talking about stepping on bugs or whatever?<p>Edit: I'd also like to point out the best way to help prevent something like this is for the parents to be monitoring what their children are doing online. It wouldn't stop all of it, after all as pointed out the contents of most if not all these videos seems rather harmless (which is kind of the point I guess) so many parents might not have issue with it, but they should still be aware of what's going on in case it doesn't stop with something relatively harmless like this. E.G. the guy mentioned in the article asking the kids to Skype with him.
