alt Hacker NewsThe internet never forgets but you could be anonymous. Or at least somewhat. But that's getting harder and harder
If such a thing isn't already possible (it is to a certain extent), we are headed towards a point where your words alone will be enough to fingerprint you.
Stylometry killed that a long time ago. There was a website, stylometry.net that coupled HN accounts based on text comparison and ranked the 10 best candidates. It was incredibly accurate and allowed id'ing a bunch of people that had gotten banned but that came back again. Based on that I would expect that anybody that has written more than a few KB of text to be id'able in the future.
