The fedeverse is an association of Reddit like social media web pages with a twitter-like interface. All fedeverse websites exchange information so your information can be seen by someone on another Fedeverse website that's creating a huge geographically and machine distributed system that is much harder to take down. Within the Fedeverse every node or website maintainer has the ability to decide who to link to and who not to link to so they can block portions of the fedeverse. So it's up to you to find the most open fedeverse node that you can find or create your own with these tools.
Poa.st is one very open one.
Many butthurt liberal Twitter userfags have gone to Mastodon which is restrictive group of nodes on the fedeverse.
