I take the essence of trolling to be the intention of provoking an angry response. It doesn't look to me as if that was OrphanWilde's goal. (I think, rather, that he was playing to the gallery, having "tried two other tactics first" and found you "completely unresponsive".)
[EDITED to add:] Of course it's possible that OrphanWilde is not being honest about his intentions, or that he's deliberately or accidentally misrepresenting his previous attempts at engagement. So what he's written is compatible with an intention to troll. But he hasn't admitted to trying to troll you, which is what I think you're saying he has done.
Ok, let me see if I understand you correctly. You do not consider abusive statements to be trolling? Abusive statements to me by their definition are meant to provoke an angry response.
Nice to get this list-style article promoting LessWrong, Rationality Dojo, and Rationality: From AI to Zombies, as part of a series of strategies for growing mentally stronger, published on Lifehack, a very popular self-improvement website. It's part of my broader project of promoting rationality and effective altruism to a broad audience, Intentional Insights.
EDIT: To be clear, based on my exchange with gjm below, the article does not promote these heavily and links more to Intentional Insights. I was excited to be able to get links to LessWrong, Rationality Dojo, and Rationality: From AI to Zombies included in the Lifehack article, as previously editors had cut out such links. I pushed back against them this time, and made a case for including them as a way of growing mentally stronger, and thus was able to get them in.
