I just posted a thread about the same topic! Personally, I just found out about the NSFW settings a few days ago. I'm designing a naughty game, and to make sure it gets optimal exposure, I'm going to to publish a CENSORED version too, which doesn't need a NSFW rating. And discretely mention that they can enable NSFW content if they want the risky version!
