It doesn't have to be. Comments such as yours add nothing to the conversation. It's an ad hominem attack. In the absence of explaining why you believe it "looks like AI", it's a baseless accusation

Implicit in "this post looks like AI"—at least the vast majority of the time—is that it is a wordy ramble with no real value because it says nothing novel or substantive—so I would not call it an hominem attack, but rather an honest criticism of the actual (lack of) content.

It has the typical patterns: em dashes, "it's not A, it's B" constructions. Also relatively new, low karma account, and its other comments are similarly LLM-ish.
