Do we know whether the people in charge of #lemmy.ml have responded about their seemingly targeted block of all #kbin instances?
Given the lack of response from the lemmy.ml admins and the fact that the issue is very much specific to their instance, this looks intentional. I hope not... seeing an instance break other instances' interactions by blocking incoming requests (while still giving their own instance full access) would be the definition of federating in bad faith.
TL;DR, this is the sort of behavior I'd expect from #Meta.
