As a former Reddit moderator one thing that was a real pain was the necessity for various spam filters. Hopefully with accounts needing to be applied for on Lemmy that’s much less of an issue.
I have noticed a dumb case where I posted something in one sub and then immediately posted the same thing in another sub which got auto removed and I had stupid amounts of karma and history so I’m surprised about that
Probably depends on the community. Being able to see removed comments and posts can be mucked up. Mostly obvious removals and/or bans but working out what crosses the line is always awkward.
I spent most of my moderation removing obviously bad people but it’s a role that forces you to think what’s just about acceptable and that’s really complicated
