It might have if I had used an algorithm that wasn’t the easiest to implement on stylometry.net. Unless you are varying your writing style across accounts a more sophisticated algorithm could very likely figure out your alts given enough comments. Which is not to say that you should give up everything and stop posting on HN but just something to consider depending on who your adversaries are.
That's kind of ignoring my original point that it doesn't matter how many of your accounts they ID if you never put your personal details on the internet.
