What you wrote before was (emphasis mine):
Abusive statements to me by their definition are meant to provoke an angry response.
and
OrphanWilde using terms like "you are creepy" to me are ad hominem attacks intentionally meant to provoke an angry response.
and I don't know how to interpret those other than in terms of motivation and not only outcome. But if you've now changed your position from "ad hominem abuse is intended to provoke an angry response" to "ad hominem abuse is likely to provoke an angry response" then we have no disagreement on that any more.
The original question was actually not about the intentions of ad hominem attacks in general but about whether OrphanWilde was admitting to trolling. Trolling is defined in terms of its intention and not merely its effects, so your change of position here doesn't alter my opinion that OrphanWilde was probably not trolling.
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.
