It depends. Did they make the children suffer?

For example if they were just Playboy like nude pictures of little girls, done in a playfull manner and with the parents concent I say why not?

As long as the privacy is there (so there is no way for scary people to look em up) and the child gets paid on some bank account she can use later in life (for her study perhaps?) then why not?

For one thing they grow up, so they'll change a lot and will be unrecognisable later in life. For seconds as long as there is absolutely no REAL porn with intercourse all that, then I don't see a problem in that.

And of course absolutely no abuse behind the scenes, it would have to all be legal. (So in this example it would be legalized)
