Maybe he was left back? Might I ask your motivation for opening this thread, Grammour Boy? If you have one in particular other than curiosity.
Because it's the internet and they could just google "porn" and come up with a lot more stuff than what is in the white room.
I have no idea, unless they're ignoring the "don't sign up unless you're over 18" proviso... but I'm sure that would never happen.
Frankly, I'd be more worried about a high-schooler that wasn't looking at the sort of porn we have in the White Room...
