A stronger plausible interpretation is that the commenter has indeed seen many instances of harassment like the ones in the OP—which was obviously her main point; that as a SaaS founder she knows about chatbots, and would have no problem with a prospective customer who just wanted to make sure a human was at the other end (obviously it would be in her business interests to engage with such a user); and that she had additional reason to believe that the person asking her "2 + 3" etc. wasn't doing so in good faith, since she wrote "kept insisting" and "it was gross".

Now obviously I don't know what happened there, but the above interpretation is not only plausible, it's almost inevitable if you begin by assuming that the other person is just as smart as you are. Instead you began by being a jerk, assumed stupidity on the part of the other, and threw in additional insults. If you behave like that on Hacker News again we will ban you.
