hey folks, we’ll be quick and to the point with this one: ##### we have made the
decision to defederate from lemmy.world and sh.itjust.works. we recognize this
is hugely inconvenient for a wide variety of reasons, but we think this is a
decision we need to take immediately. the remainder of the post...
They said it's mostly about the amount of moderation action they've had to take against users from those instances. Maybe lemmy.ml has less users who behave badly outside their server?
I could also see there being a reticence to defederate from the "canonical" instance so to speak.
lemmy.ml is significantly smaller because they chose to point users to other instances and even closed registration at one point to ensure that they could continue to keep up with demand.
