Moderators are part of the problem really, there are a handful of moderators holding the reins over all the popular subreddits, and "smaller" (even big ones) subreddits suffer from the same problem.
As an example, r/MistralAI, r/LocalLLaMA, r/ChatGPT, r/OpenAI and r/grok are all run by the same person.
The only survivable places on reddit left are the subreddits with small amount of contributors that aren't trying to gain something by participating and organizing. But they're so few.
