Communities in Lemmy/Mbin are not federated by default. So when you create a new community, it will only be available to your instance. At least 1 person from all other instances must follow it in order to make it available. This tool does that. It follows your community from all remote instances until at least 1 other person follows it.
What’s the deal with lemmy.nz on this? They’ve registered their instance but also blocked it??
