Great. There is also the ability to block instances. You wouldn't have to block every community directly

Are you sure that's not a feature on the app you're using? How do you block an instance? It's frequently one of the most talked about missing features.
At least when using Lemmy through browser, there is no functionality for an user to block a whole instance. Instance admins can only block whole instances. Third-party clients may have that functionality. The main reason why Sopuli is defederated from LemmyNSFW is that they allow porn, and Sopuli doesn't federate with instances that either allow porn or are dedicated only for it.
