Here's a comical one:

> The discussion on Spanish traders set the standa raises interesting points. In practical applications, the key challenge is balancing performance with maintainability. Would be valuable to see more concrete examples of trade-offs. [emphasis added]
They glob out part of the submission title (and took too much and cut off in the middle of a word) generating a delightful nonsense descriptor (the italicized bit). The title being:

I'm the one who vouched it. I don't check commenters' history before doing it. Maybe I should. My LLM-detector is apparently broken (especially on short posts). At face value I saw nothing wrong with it, so I vouched it.
1. There's a problem with the account (and then inform them and maybe notify the mods myself). Sometimes people get shadowbanned without good reason (usually the result of automoderation, not an explicit human moderator action) or for something that happened years ago, but their history is pretty clean since.
2. To see if the person is just a spammer (as is the case here).
Though I only do this if the comment seems like something that oughtn't be dead (as this one does on a first glance). The comment is shallow, but not necessarily wrong or bad. It just adds little to the discussion since it boils down to "The book is an introductory text." which we also get from reading the submission title.
The last 3 years was a paradigm shift. How do you know if a comment was generated by AI? If it's written Better than a human comment... if it's too good.
