By refusing to follow the rules of putting the NSFW as the first tag, I don't understand how this site can really legally stand behind the fact that kids are on here. It's actually a legal issue: only sites that are 18+ can have hardcore porn on them. Obviously the developers need to find a solution to this or else there could be a legal mess in the near future.

I encourage you to read up on the latest in legal developments in the US. What you say does not seem to have basis in law.
