it's up to ernest ofc but imo closing signups kinda feels "un-kbin". fearing defederation from beehaw is just silly. they will do what they will do, and imo it's pointless to try and center kbin's actions on those of an entirely different site and instance.
if the influx of people is making it hard to do admin stuff, then I guess it might be necessary, but simply to "spread users around" I don't really support. If people want to come to kbin.social, let them come to kbin.social.
