little has been done to mitigate it

They made it more difficult for community to spot bots. Now anyone can hide their profile post/comment history. By design!

pretty much for every legitimate post a day, you’d get 6 to 10 bot posts

Real! I once saw a post in some sub where mods were complaining about bot/AI problems lately. In comments there was a guy who said he is moderating a very niche sub about toyota trucks with a few thousands of users. He said that half of the posts in a day feature AI generated pictures of these cars. Can’t be real people posting it. I wonder what really happens in bigger subs.
