/kbin speaks ActivityPub but is an entirely different software stack. It has some big bugs with federation (specifically around admin actions like spam removal).

The primary instance (kbin.social) also doesn’t have a very good team of mods/admins keeping up with the influx of spam.

Lemmy was about two years old when the reddit exodus happened, whereas /kbin had only been around for about a month. Its sole developer/admin is very overwhelmed just trying to keep everything running (and trying to, you know, live).

The project needs help, but I don’t think Ernest has enough trustworthy people in his circle to delegate responsibilities.
