I've only been back to visit a small, private sub, but I've seen a lot of posts here saying that a high percentage of bot content is obvious. The conjecture is that there's always been a lot of bots, but they were somewhat less obvious because there was more human content. With a lot of big content creators leaving, it's more apparent when a lot of posts and comments are from bots.
Plus some people think Reddit has increased bot usage to astroturf against the protests and to give the illusion that traffic isn't down.
The small communities I look at are half of what they used to be. The bigger ones just made up for it with increased bot posting.
The bot posting will probably last long enough for their IPO so they can sucker in enough investors for them to fuck on out of there. The more casual users that are left probably don’t use the system enough to know/care until it comes crashing down.
