I have a noob question. From a technical point of view, why does it matter to server A (beehaw) whether server B (world) federates with C (exploding nazis) or not? Since A is defederated from C, the content should be unavailable anyway. I completely get why a proper moderation of B itself is crucial, but what B federates with should be irrelevant if B itself stays "pure", right? Again, from a technical point of view, because otherwise willingly federating with nazis obviously strongly correlates with allowing nazis inside. To reiterate, how is A directly affected by what B federates with? Is it merely a matter of lobbying or is there some technicality I'm missing here?
