It was because lemmy.world was experiencing explosive growth and did not have a good mechanism in place to limit spam and troll accounts. This combined with Lemmy’s still infant moderating tools made it difficult for Beehaw to contend with the influx of lemmy.world users who were harassing beehaw users.

A mutual decision was made between both beehaw and lemmy.world to temporarily defederate while the moderation tools are worked on. They fully intend to re-federate once these tools are in place, as both instances have a fairly similar attitude towards harassment and hate speech.

There was no disagreement between the admins of beehaw and lemmy.world
