I appreciate kbin a lot and I hope Ernest will get back to development when he's ready, but I don't think it makes sense for him also to be responsible for administrating a major instance. That's a huge job.
I'm not entirely sure where I'd move to yet, but if kbin.social is not properly moderated it makes sense to go elsewhere. At some point other instances might have no choice but to defederate.
That's different from giving up on the software - I do still appreciate Kbin a lot. :)
