I have the exact same frustration. Reddit has been a complete mess for years. Unfortunately, Lemmy is only slightly better, and still seems to be astroturfed and filled with overconfident, unintelligent people who spread misinformation. I shared the link above on one of the /c/reddit lemmy communities and it was heavily astroturfed and then deleted by a mod for a ridiculous reason.

I posted in various other communities about a completely different topic and the only intelligent response I received was a PM.

I’ve blocked close to a hundred “fluff” (low-quality) communities on Lemmy, so my feed is highly curated. But the fluff/low-quality communities vastly outnumber the high-quality ones.

People keep making threads about this, and speculating that Lemmy might be astroturfed by people who don’t want to see it succeed. Unfortunately, there doesn’t seem to be a viable solution. You would need extremely competent and active moderators, or we have to wait until AI becomes advanced enough to neutrally and accurately moderate.

This is one reason I opted to move my Reddit communities to a forum instead of Lemmy. The problem with that is small forums don’t show up on search engines. Some forum software teams are joining the fediverse though, so that should help. But not all forums have intelligent people either, so it’s definitely a struggle to find these days.
