At the moment it's a few brand new accounts posting essentially the same content-less statement that covers the big points in the headline {novelty, pollination, frog}.
Example:
That's amazing! It's incredible that we are still discovering new species, and that some of them can even have special abilities like pollinating. I'm looking forward to reading more about this frog.
I wonder how well /r9k/ would work on substrings. It seems like these GPT robots are roughly as good as taking all the random text in a google search taglines and making a sentence out of it.
the point of the bots isn't posting about frogs, they are posting about frogs to (badly) look like users that have normal activity when they do start spamming or mass-upvoting.
When it's consistent groups of 4 brand new accounts all making essentially the same comment at the same time (in multiple places) it starts to get pretty suspicious.
Kind of concerning that "hey that's pretty neat" comments are immediately suspected (probably accurately) of being bots. A comment like that example isn't useful to the other comment readers, but it's probably pretty motivating to the author, and it makes forums more positive places. Removing the organic versions of those will make forums a more negative place, and that's a shame.
I'd be more accepting of a "hey that's pretty neat" comment if it didn't read like the equivalent of a middle schooler's attempt to restate the headline as if they read the article (with some hallucinations, such as this being a newly-discovered species).
Edit to add: Sibling comment has me questioning whether I'm a robot
when I got a pleasing reading experience from HN, I can't leave some comments like: this is so cute/a good story...
this always get so many downvote haha.
