Ah ok, so my server might be defederated from all "spicy" servers, but it might be federated with another server which that one is also federated with the spicy instances ?
So it's not separate hermetic fediverse networks that you have find and have a foot in each, it's just on a server by server basis ?
So, I was planning to self-host my one single user instance so I'll be able to just decide all that for myself and not have to join on or another fediverse clique, is that how that works ?
