Because I refuse to give up on speaking the truth about the matter, and how corrupt the admins are, and demonstrating the very serious flaws and problems Lemmy as a platform has (there are a lot of ways people can exploit Lemmy to be a massive douche canoe, for starters).
Because truth is valuable for its own sake even if no one will listen.
People really ought to go back to separate websites and small forums, and get away from federation in general. It doesn't do any real good.
Nominally, you'd need to go through some request process to request federation with other large instances. Then they'd vet your configuration before adding you.
Would be nice if they had some form of agreement where you can get accepted by one big instance, you get accepted by all. Or maybe even a standard order form and application which you can send to all major instances with the click of a button
Lemmy supports both blacklist and whitelist federation, but the only large instance that uses whitelist federation as far as I know currently is Hexbear.
