Nope. But it's not only children who are raped or killed.
Isn't it equally likely that a person who downloads porn from a teen website may rape or kill teens? That seems to be your argument for intervention.
My arguement for intervention is that A.) Child porn is illegal and B.) Sex with minors is also illegal.
To my knowledge sex with teenagers (18 or over) and MILFs is legal.
If you can produce any laws that say different by all means produce them.
