We would love to see hyperlocal Mastodon (or other fediverse software) instances. See https://www.empathyforward.org/2025/12/community-based-fediverse-instances/ for more thoughts on it. Of course, there are responsibilities.
We’re working on a service that can help manage the list of blocked and limited servers to make it easier to create a welcoming community. We are also considering adding some spam detection abilities as well.
What other services would help you create a great Mastodon community?
