Yes, but It does bring up some interesting questions. How would they keep track of whos a teenager? What happens to the pictures obtained from sexting when the teens are adults? All those picture would count as cp wouldn't they?
The more ridiculous and specific the laws get the better as its bound to fuck someone whos not a pedophile over and force people to reevaluate what they're doing.
If any of us can, we should try our best to make these laws even more strict and excessive.
