I'd be interested to know why those comments were flagged actually. They don't scream AI and no-one has replied calling them out as AI, etc. But the vast majority are dead.

> four bland messages

That's why. Boring, bland, etc. That account's M.O. is basically "write a paragraph that says nothing." Fwiw, I do think AI can be indistinguishable from dumb, boring people, but usually those kinds of people won't be on HN.

The account was immediately shadowbanned after re-awakening from a long period of inactivity.

I agree it doesn't seem obviously AI. The early comments are all in the same writing style and smell human. Lots of strong opinions e.g.

"logged in after years away and had basically the same experience. the feed is just AI slop and engagement bait now, none of it from people I actually followed." [about Facebook]

HN has got a big problem with silently shadowbanning accounts for no obvious reason. Whether it's an attempt to fight bots gone wrong or something else isn't clear. By the very nature of shadowbanning there is no feedback loop that can correct mistake.

		Pretty sure they weren't shadowbanned immediately, since people replied to some of those [dead] comments. Most likely the shadowban was applied retroactively after posting the more obviously generated stuff.
