Many federation things are broken atm. i know of Multiple communitys that are behind hours or Multiple days both on lemmy.world and Kbin the instance owner says their server got tons of recources free so its federation related bugs i guess.
maybe never, this is going to be a thing on and off with the large instances, get on a smaller one with a neutral rep and youll be able to interact with the whole fediverse as long as you don’t cross lines.
You can see the list of blocked instances at /instances.
They are currently not blocked.
A fix for this was introduced in 0.18 and another one in 0.18.1. Version 0.18.1 is in release client 4 now, and lemmy.world just updated yesterday. Lemmy ml is still on 0.18.0 and doesn’t have the 2nd fix yet. There are likely to be many causes to this, but consensus seems to be that federation has drastically improved since world upgraded to 0.18.1rc-4.
So, what to do? Just be patient. These are growing pains and known issues being tracked by devs and admins across instances. If Lemmy.ml and Lemmy.world wanted to defederate, they would do exactly that, instead of some silly shadow-defederation as you’re suggesting.
