You could make some options in game for the adults who want to be adults. 1. You could make the room to where you can enable an option for 18+ for events that might be playing unclean music. Something you can toggle on and off. 2. Just to ensure that they are over 18, you could make it to where if you pay for premium you get access to those features. That way young people can still come in and play around but adults can have their own space, but when they are done they can open the room back up or they can leave it closed.
