@misslav Gab is a social network very much like Mastodon and Twitter. People who are banned from Twitter flee to Gab and most of those people are right wing. Jack Dorsey, who owns Twitter and is himself quite left wing, is attempting a purge of ideological opponents on his site. Recently Gab has announced that it will be switching from using it's own software to using Mastodon and will likely become part of the Fediverse.
