The post in the screenshot was from January; the original poster has since been suspended for a reason I could not find, even with reveddit. Since then, the same 6 accounts mentioned above seem to be in some sort of limbo, as most of them have been suspended, but still post the same topics regularly.

If you look at the comments of the most repeated posts, there is some acknowledgement of the constant reposting (“Mom said it was my turn to post this, blahblahblah”) before being derailed back into the slop in question, but oddly enough, I have not seen any comments directly calling out the sub for botting. I did find one post on the sub itself that got little traction before it was deleted by an automod.

Looking at other subs on the subject, it seems that several people have been quietly banned from the sub for making the same observations. My guess is that joking about people rehashing topics is preferable to people coming to find that your entire subreddit is some sort of psyop.
