Simplifying Complexity, One Answer at a Time!
Rules
Off the top of my head...
It can definitely be a thankless job at times, but also very rewarding to see the community flourish.
I realize this isn't an ELI5 explanation, but https://join-lemmy.org/docs/en/users/04-moderation.html is a good, basic primer on moderation in lemmy.
I imagine the types of actions you'll do is similar to what can be seen in sh.itjust.works/modlog . It'll be less work in the beginning when you have only a few users, but no one's gonna blame you if you stop. Well maybe you'd want to pass the torch to someone first.
Not specific to Lemmy, but basically you remove spam, offensive posts/comments and cultivate the space the way you think it should be.
