We have no proof that this is even Anonymous. We have nothing that says that the author of this is even a hacker or knows hackers. Any person following the Anonymous attacks and statements could have easily written this file.
Why is this on hacker news? This is not news, this is a poorly (tech wise) written short story.
Anonymous isn't a group, it is a meme, and so it doesn't make sense to say that someone could be impersonating anonymous.
I agree that non-credible claims under the Anonymous meme should be hidden here if they don't have a significant enough following to be newsworthy - the use of a particular meme does not automatically make something newsworthy.
