Well, I opened a Social Group named D&D just for adult RPs and what not. So that means there is a group you can join (and need to join) if you wish to view the content. That keeps the 'dodgy' stuff out of prying eyes of youngsters. We need to remember we are a support community and having a whole forum dedicated to getting your daily fix is counter-productive to whom we are, which is why, in an earlier post within this thread, I stated no against this.
Even if it WAS kept clean, we'd attract the wrong people with the concept of such and it'd add an even bigger work load to our mods, so even still, I'm not up for this, even if I have the bias that I own a social group that could support such.
