Yeah thats why defederation isn't as bad of a decision currently while things get coded. It ruins a bit of the fediverse mechanics though of only needing one account to interact with different sites which is why having them able to interact in the instance communities while their outside posts are hidden is ideal

The main sorts used in the instance are local new, local active, and subs which is what we are mainly optimizing for. Default sort when people make an account is local active which is a bit different from most other sites that default to all so it hasn't been as big of a problem for us as other instances but since we're growing more and more been working on some different guidelines for things like bots, federated instances, etc slowly on the side
