The guy has a ghost ban on Hacker News. He was banned for some other comment. He doesn't know that no one else can see his post.

Probably not hellbanned, maybe spam filters gone wrong. I vouched them back into the land of the living :)

Thank you :)

My best guess is people think it's AI written? I mean, I kinda get such vibes from it, but it (IMO) could also be human written.
