Think about it; instead of those in charge or the instances deciding who they don’t want to be federated with and thus restricting content for the users, it would be better if users were able to block entire instances instead.
We’d be able to curate our own browsing experience so much better without admin/mod drama influencing the rest of us.
Edit: Alright so maybe not exactly replace defederation, but it should still be an option available to us, and in general should become the default action before defederation IMHO.
I’m sympathetic to the idea that an individual user should be able to override their instance admins’ preferences on access for content-related reasons, but I don’t think it would be workable from an administrative viewpoint to allow users to allowlist instances that were blocklisted for administrative reasons.
Lemmy.world dealt with (and is probably still dealing with) a series of malicious actions designed to actually bring down the service or otherwise tie up its resources (including moderator/admin attention and effort, and exposure to literal criminal charges), using maliciously crafted requests to bring down servers, literally illegal content posted to their servers, etc. Defederation in response to these types of attacks would be defeated if a user could let the content come through anyway.
I imagine most instances are dealing with similar issues.
So ideally we’d need to be able to create 4 categories of relationships with other instances:
But I think you’d find that the typical scenario that justifies blocking would actually put the typical block into category 1, not category 2.
