There's still a few things I don't understand about Mastodon and the Fediverse. Like - for the instance I am on, how can I see what other instances it federates? Are there ways to see if there are other servers which block it?
@planettimmy@drashvr federation is on by default, but you can check the /about page of any server, there is a list of ‘moderated servers’ which it limits or blocks. Somewhat harder to do the reverse!
