Fandom is largely about the extrapolation of characters in the show into more complete worlds.

I think we can agree on that. It's just that extrapolating into some of the worlds troubles me.

As far as I can understand, curation and rating systems should exist to give reader the freedom to read what they want to read (and avoid what they want to avoid), not take away any freedom. I would prefer they include everything, just label it appropriately; and that's what curation should be good for: to make sure everything is labelled consistently whether or not every individual author does so.

Now that I think about it, I notice (yet again) that I hardly know a thing about state of censorship and ratings (is it how they call this "rated M for mature content"). I wonder, what is the general consensus on all of that and how it evolved over time? I already thought of maybe finding a book on it, or something, but it looked like stupid way to spend time so I didn't. Individual articles like [url=en.wikipedia.org/wiki/Hays_Code]Hays Code[/url] don't give the full picture.
