Gotta say it.
You play this game at your risk. You need a credit card, thus, you need to be either 18, or have consent of someone older. If theres swearing over the txt, well, grow up.
HOWEVER, on the flip side, if YOU are swearing, and someone tells you "Hey, theres a kid in the room", youd better be able to shut it up. At the very LEAST on VOX.
Basically, it comes down to courtesy. I think if your gonna swear over the text, fine, kids cannot 'overhear' text. DONT swear over VOX, or at least try to avoid it.
