Why not remove them as mod? I don’t understand why you would keep anyone in the mod team that has been banned from the community?
Oversight - that simple.
Yes that is a problem with Lemmy in general. But why this only seen as a problem for people from Lemmy World and sh.itjust.works?
That is not actually a problem with Lemmy in general - community bans do block posting unlike site bans. As for why, well, it was done at that point in time because Lemmy.World and Sh.it just.works took a lot of moderation time - for one reason or another, bad actors liked to go there. I have no reason to believe this has changed now that .World is now many times bigger than it was.
Why ban for 9999 days if you can leave it empty and perma-ban?
Oversight or malice. You can break the modlog of everyone you’re federated with because of this - that is dangerous.
But Beehaw defederated from Lemmy.World and sh.itjust.works very early on and in the meantime they are federated with instances that are as big as Lemmy.World was back then.
Size doesn’t necessarily mean problems though. I think it’s probably a culture problem as the root cause but I don’t think .World wants to tackle that problem so all I can do is wait for better tools.
