5 without a doubt. This is the article that represents OI's Illuminati-NWO-paranoia-/x/ premise the best. Definitely the most ambitious thing on the website: four pitch-perfect author voices (five counting the video), incredible use of multimedia, a massive premise. I'm not surprised that the dude has been working on this (more or less) for 2 years.
However, I don't get why the Fée Moderne puzzle is so obtuse: it unfairly hides some of the best writing on the website. It could use a guide like RPC-000 (which wouldn't break immersion: I am reading this article on a website called wikidot.com and am one click from a massive .jpeg of Martin Scorcese). The Johnny Law puzzle is perfectly fine, though.
Despite that little complaint, this is as good as digital fiction gets.
