It sounds like you've received a comment from an "NPC human".
An example of something that happened to me:
I was engaged in a "flame war" on a (very) high-temperature gaming forum (EVE Online), and at the time it made sense to react to every "sniper".
I got "shot at" by an obvious late-teenaged boy (plenty of those play EVE), and used my reply to make a wider point (for the whole thread) that indirectly pointed out that I wasn't impressed by what he said.
He couldn't find a way to counter attack (basic flame war technique: always write defensively), so he attacked me for my
grammar /lol.
Obviously I don't make my living as a novelist, but I've written courses, a couple of technical books, many presentations, and thousands of business emails. None of it is art, but I know my grammar is ok.
On point: you probably induced the same effect. Someone who couldn't find a way to refute your point or attack you personally, and is dumb enough that they "brain-locked" themselves (a kind of mental tantrum in this case) and attacked in a way that, on second glance, is obvious nonsense .
In that case, your AI accusation was like my "illiteracy" accusation. Essentially the poster signaling their own stupidity
You can take the win (because it was a win - your attacker made
themselves uncomfortable doing that).
Or you can nuke them.
I prefer to leave that kind of thing hanging, because the discomfort doesn't go away immediately: unresolved "cognitive dissonance" takes a while to wear off. If you nuke them, they get a brief period of marginally higher discomfort which is then resolved quickly.
(BTW - polite "nuking" isn't particularly difficult, though like anything else there's a "startup cost".
For example you could "pretend" to actually be an AI, briefly "analyze" their post, and "reject" it for inclusion into your AI knowledge base it because it's entirely content free.)
Polite, potentially amusing for the others in the forum, plausible deniability, and quite difficult to respond to, since the actual refutation ("I'm not an AI") is masked. But to the other poster it will
feel like an
ad hominem, with the added possibility of frustration that they find responding difficult.
Full disclosure: I used to enjoy that kind of thing. I lost interest and opportunity when I stopped online gaming, but it was fun at the time
