I advise checking out the users other comments before jumping to conclusions. Doesn't look AI generated to me, rather just an "individual" writing style. Only because it's possible doesn't mean its true. Maybe user can confirm?

sounds like the “eigenprompt”

Hm. Not convinced. What makes you so sure?

Otherwise just downvote or flag I guess, but this comment of yours just reads as an insult to a person that maybe did not put the most effort into writing their comment, but seems genuine to me at least.

The now removed stuff, in the original, talking about a blue whale was somewhat odd.

Ok, if there was more and weird stuff, that now got edited out(after being called out?), that would be a different story.
