For sake of new users we use posts like this to redirect people to more active communities, sticky the post and lock to mods-only: https://threadiverse.link/sopuli.xyz/post/31536406

Edit to add: its incase something happens in the future and we want to reopen the community with new mods. Instances come and go and there's some fediverse bickering every once in awhile so the communities split. Then there's a ready community.
