Well its a push pull. Those who might mod are typically far more engaged, and its a thankless job. Its not something that can be easily automated and there is real important work around true bad faith actors trying to derail the entire platform/ fediverse.
Its also important to acknowledge that its a balancing act, and that frankly, I think if you are a mod for a community, maybe you should't be allowed to participate in discussions in that community?
Its like, if you are playing pitcher, you shouldn't also be calling balls and strikes. More broadly, its something we'll need to keep iterating on and thinking about as a fediverse; it goes beyond lemmy and extends to the entire principal of large scale social media.
