Scuttlebutt is an off-grid P2P social network. https://is.gd/1XuaNq
'Secure Scuttlebutt is also different to federated social networks like Mastodon, Diaspora, GNU social, OStatus. Those technologies are not peer-to-peer, because each component is either a server or a client, but not both. … [T]here is still trust and dependency on third-party servers and ISPs, which makes it possible for admistrators of those to abuse their power, through content policies, privacy violations or censorship.'
