@williampietri i mean, currently, that same problem exists here as well. We can defederate the nazis, but they still get to do and say bad shit on their own instances. But there is value in defederating those guys and letting them stew in their own little cesspools rather than harassing people.
But we can also envision more automated systems that are tracking the cesspools for evidence of harms and look for ways to counteract it as well.
