If you look at the replies to basically any big post, you'll see all the blue checkmark bots in there. Usually just copying posts, sometimes doing a weird ai summary of the original post in a way that isn't actually replying to it.

I've got no idea if they're somehow making money off it or what's up

Followed by the porn bots, the racist bots, the "American" bot, etc. I'm really surprised how someone can use X and say that it is not full of bots. It's the same on Reddit.
