I think you're talking about people who aren't in the conversation though: everyone who would be involved in this thread maintains a substantial block list, even if we have different standards for it. No one here is going to suggest a 100% open Fedi.
Our issue is the number of new and marginalized instances that are going to find a chunk of the network cut off by this sort of thing. We want new servers to be made, and we want those servers to thrive, because new servers add new life to the network, and a very important part of both of all of that is that good posts need to be able to spread far and wide and fast.
The Content Must Flow.
How does one create a new marginalized instance in an environment where instances with great content from marginalized groups is going to be cut off from them for however long it takes to get on the list? How do we let people on these new instances know more content will come, and why would they join a server that's blocked off?
