The problem is the bots make more posts than there are people willing to comment on anything. The userbase gets fragmented and they never end up in the same post as someone else, there's 0 actual socializing. People scroll past tons of posts with 0 comments and get frustrated and sometimes they quit. It also discourages real people from making regular posts because they can get drowned out by the bots.

I'd be very curious to see if there's been any successful Lemmy bot poster that just copies content from Reddit or somewhere else, in a way that people actually enjoy and engage with.

I think you need to respect the natural ratio of people posting and people commenting. Bots screw up that ratio big time and dilute the commenters spread thin, stretched across too many posts. Like butter scraped over too much bread.
