alt Hacker NewsI have a couple posts on reddit that didn't receive a lot of comments but every week or so it'll get a comment that is some GPT-powered bot going, "<topic of post on reddit>? Wow! That's really thought provoking, I wonder about why <topic of post on reddit> is important," and so on, asking me very obvious questions in an attempt to get me to feed the system more data.
I wouldn't be surprised to find out these bots are actually being run by reddit to encourage engagement.
See the history of Reddit. It was manually curated sock puppets before bots were viable, and now that bots are viable, I strongly believe the bulk of comments and posts in the popular subreddits are bots (and many are run by reddit themselves).
