I’ve come across some inactive communities on instances other than mine. A few I’ve thought would be worth restarting but I’m not sure how this works on Lemmy.
Alternatively, I thought about starting a new community under the same theme and growing a community there but, again, I am not sure if everyone is free to start a community or if it is something that you have to gain approval of your instance first.
Yes and no. The short answer is that there are limits to federation. But you don’t need to match the instance
Edit: honestly, the issues persist regardless of the moderator’s instance. It’s more so about the user’s
