You're overlooking the fact that tons of people around the globe (in different jurisdictions) just label their content 18+ by default just in order to not be liable for anything that could be construed as "not for minors". And I really mean anything completely tame by most of civilized countries standards, let's say swearing or pixel blood. Of course this isn't a great solution but if you don't create your content to cater to the mass market by default, but just to put it out there, it's suddenly not your problem anymore if anyone under 18 clicks through the "I am over 18" banner. Yes, it's stupid but my point is - just because it's labeled NSFW this doesn't really mean there is anything that sensible adults would deem NSFW.
