A good example is https://lemmy.world/c/documentaries
One of their mods, https://lemmy.world/u/sabbah, currently mods 54 communites despite only being on Lemmy for about a month and has never posted on c/documentaries (except for his post asking for people to join his mod team).
The other mod, https://lemmy.world/u/AradFort, has one post to c/documentaries and moderates 18 communities.
Does Lemmy.World have a plan to remove this kind of cancer before we start getting reddit supermods here too?
Edit: This comment shows how this is even more dangerous than I had thought.
Edit2: Official answer from LW admin is here
Lemmy is still small enough that you may just be getting lucky with everyone behaving themselves. If no one is reporting anything, just try to stay in-the-loop with the general goings on in the community so you can jump in if something does happen.
