Has Hacker News ever been 'trolled' (/b/?)?

Don't ask me about the prospect of a Wikipedia contributor coming up with the idea to research 'troll'?

(On a side note: my name is Alex, and I'm a freshman studying CS at Harvard. I'm trying to spend the free time that I have actively engaging on things that I think are important on the internet, like Hacker News, because I want to be a better global citizen and I think that thinking analytically is a necessary condition to do so. I'm just diving into the world of computer science, so I'm excited to ask and hopefully have answered a lot of questions that I'm generating. Thanks!)

This submission reeks of self-reference. While referring to the phenomenon of trolling, it may itself constitute a troll as the term is defined (i.e. by "sow[ing] discord on the Internet by starting arguments or upsetting people)."
