Mastodon is an ethically-designed, open-source microblogging platform consisting of a network of independent servers that talk to each other (the "fediverse"). It can be thought of as an alternative to Twitter, for example. This particular server focuses on two things: First, fighting oppression, exploitation, abuse and victimization, whether of humans, plants, animals, or the planet itself. Second, helping people heal from any of the above that they have experienced or witnessed.
