A user cannot downvote a comment that’s directly in reply to their own.

It was likely other user(s) who downvoted a comment that they perceived as low-effort and adding little to the discussion, which I could easily see if the entire comment was something like “Such as?”

I see, thanks. FWIW I was succinct because I didn't think a comment to the effect of "I prefer to let AI do my thinking for me" merited a substantive response. I was (and still am) also genuinely curious what these 3-5 examples were. South Korean chaebols? Roman latifundia? Perhaps we'll never know
