I see a lot of communities that had no interaction in years. Also some community creators/moderators are inactive in the Threadiverse since the creation of the community.

So my questions are:

1. Are communities kept forever also if there is no interaction for years?
2. Are communities kept forever also if the moderator isn’t active anymore?
3. Inactive communities can be spammed since there is no moderation?
4. Is there a way to add a new moderator if the moderator of a community isn’t active anymore?
