So several smaller lemmy instances (like sopuli, ani.social, reddthat, etc) are having some serious slowdown issues right now and are having delayed federation with lemmy.world. From what I understand, the suspected cause is a kbin bug, where it's glitching out and spamming the fediverse with infinitely repeating federation updates. Several lemmy instances have blocked kbin over it (including lemmy.world and sopuli), but it's still causing issues and slowdowns.

There have been multiple attempts to reach the admin for kbin about it, but his developer accounts seemingly went dark 4 months ago (according to his commit history) and he's not responding to any messages. Mbin has seemingly already patched it according to their resolved issues/pull requests, but it's looking like kbin may have to be cut off from the rest if the fediverse unless the dev resurfaces.
