I think you’re wildly overestimating that timetable - over on that site I’m a member of a sub where you need intimate knowledge of the subject to moderate it effectively (and because of the nature of the subject it gets a lot of trolls to put it mildly). With no community mods that sub would become a cesspit within days, as would subs that are currently the focus of the alt-right, such as science, LGBT subs etc. It’s going to be a bin fire if the community mods leave - you’ll feel so dirty you’ll have to take a shower after every visit to your previously favourite subs…

It’s a bit worse than that actually. I’m now seeing several communities with exactly the same name that originate on different servers - so clearly Lemmy doesn’t have a rule about duplication once you cross a server boundary. That’s going to get unwieldy quite fast particularly if, I dunno, “Aww” gets popular on two separate servers at the same time - I guess I’ll have to subscribe to both…
