Well.. maybe this helps..

Although it doesn't touch on the issue of a "Reality Site"
When you mentioned the layout being required.. I got to thinking..

In the definition of reality porn listed above, it is said:

"staged scenes, usually shot in cinéma vérité fashion, set up and prelude sexual encounters."

So then perhaps a Reality Site requires that the scenes be set up via text, with the scene then watched.

A good example of this might be boyscasting.com (though I might be a little off on it)... it sets up the site itself with a little story.. then explains the encounter for each video... While the video itself is shot in a gonzo-ish style.
