The purpose of the profanity filter is to prevent new people who are either unaware or don't care about the chat guidelines from exposing #global to profanity. Making an opt-in adult chat room would do nothing to help with this. These people would still be accidentally (or not so accidentally) using profanity in #global before even having heard about the room.
Probably the better solution is to have an option to turn off the profanity filter in the game's options. This way people who are willing to be potentially exposed to profanity can disable the filter. Troublemakers would only be exposing these people to the profanity.
