Sorry for being a bit harsh, but I have little sympathy for the admins of lemmy.world. Instead of looking for ways to disperse the people around other instances, it seems that the people behind .world are rushing to grab mindshare and concentrate as many people as they can in their own servers.
The threadiverse is not healthy when almost 50% of the active user base is in the same instance. The lemmy.ml admins basically shut down their instance for registration and said "please look elsewhere". Why can't you do the same?
