It's a silly thing to even attack, and that doesn't mean be ok with it, I just mean that shortly, it can be generated on the spot, without ever needing to be transmitted over a network or stored on a hard drive.

And you can't attack the means of generating either, without essentially making open source code and private computers illegal. The code doesn't have to have a single line in it explicity about child porn or designer viruses etc to be used for such things, the same way the cpu or compiler doesn't.

So you would have to have hardware and software that the user does not control which can make judgements about what the user is currently doing, or at least log it.
