It sounds not like a bad idea, especially for increasing player bases and some new incomes for devs. But imagine everyday there's 10 trolls, monkes and colders smashing in your room,trolling and hugging around, stealing your ideas, rooms and creations, spamming "send nude", "wanna have some sex?", throwing out some cheap RPs, endless colds or even advertisement links... That's what happened at SL and MnFclub ... maybe it's not a very good idea. Even there is a possible way to add an purchasable adult content pass for all sex/nude contents like iMVU to filter out trolls, but still... what can devs serve after filtered most of poses, some of clothing and almost all player rooms for f2p players
