Well ...
I believe this game is for 18+ ... so no responsible parent should allow his child to be anywehere near. O_o
It sounds kinda funny to me ... like demanding parental control being aplied to hardcore fetish porn movie.
But on the other hand, if you are player parent yourself you never know when, how, or whence those little rascals get to your room ... especialy if you are that kind of player that plays with headphones on ...
So i gues +1, this cant harm anything and it can help someone, so i dont quite see any reason why not. ^_^
