Thank you for this report. It will help in seeing the wider picture of the Fedi and oprn social web.
I still remain resistant to allow-list based federation. I worry that doesnt reduce the work load. And makes the open web less open. If open at all, truely.
But, reading this, i do recognize there is a problem that deny-list is poor at solving.
If there is a answer that is degrees before allowlist only, I could be open to it.
