Gregory's Server@Matt_Noyes The German servers https://geno.social/about/more and https://hostsharing.coop/about/more are run by the hosting cooperative Hostsharing.
The first is the home of cooperatives in Germand speaking countries, the second is for the members of Hostsharing.
@juh thanks, do you know if the Mastodon instance admin and moderation is done cooperatively?
