I.

From Vox: Solving The Mystery Of The Internet's Most Beloved And Notorious Fanfic. The fanfic is "My Immortal", a Harry Potter story so famous that it has its own Wikipedia page, and articles about it in Slate, Buzzfeed, and The Guardian.

It's famous for being really, really bad. Spectacularly bad. Worse than it should be possible for anything to be. You wouldn't think you could get The Guardian to write an article about how bad your fanfiction was, but here we are. Everyone agrees that it must have taken a genius to make something so awful, but until recently nobody knew who had authored the pseudonymous work. The Vox article investigates and finds it was probably small-time author Theresa Christodoupolos, who goes by the pen name Rose Christo.

But this leaves other mysteries unresolved. Like: what is going on with it? Its plot makes little sense – characters appear, disappear, change names, and merge into one another with no particular pattern. Even its language is fluid, somewhere between misspelled English and a gibberish that can at best produce associations suggestive of English words.
