Defederation I believe is a really powerful tool. More so than it seems. It creates islands of a sort and you can be more or less assured that your interests are respected. If they're not you move to an instance that federates with likeminded individuals. Makes it so much easier to isolate bad actors since they tend to group together. And then you disconnect from them and suddenly a whole avalanche of problems simply goes away. Moderation is obviously necessary but it is much more of a community effort. Keep in mind that most admins and mods are here because they want to use the forum just like you do. Your interests align much more than if a vc backed company Hosts your community with the singular goal of extracting as much value out of you as they can in whatever way available.
