People on reddit always make the assumption that bots are all going to be angry divisive posts or posts advertising products but this is by far the most common form of reddit bot I see: the kind that just posts a bunch of one sentence generic positivity comments for easy upvotes where every post has the exact same grammatical format. My favorite is when like four of them post in the same thread with barely reworded versions of the same comment. I’ve gotten a good read on them at this point and I notice them constantly.
