I apologize if this has been asked before, but I’m wondering if it would be feasible to implement a new approach to defederation that offers the option of choosing between complete or partial defederation from another instance.
Currently, defederation blocks both the locally made posts on the defederated instance and its entire userbase. This can be excessive, and in many cases it may be better to block only the posts made on the other instance while still allowing its users to interact with the instance that defederated — user behavior may differ between their home instance and other instances. This partial defederation (or limited federation) would facilitate normal interaction without negatively affecting the content of a feed.
Problematic users could be managed on a case-by-case basis using bans, similar to how it is done for federated instances. Automated tools could simplify this process in the future. Complete defederation would still be necessary in extreme cases where no positive user interactions are expected, such as with instances that promote Nazism.
Instances are being forced to choose between a sledgehammer and nothing at all, and I think a compromise is warranted. I’m curious to read others’ thoughts on how to solve this existing challenge.
EDIT: I added a rough sketch that outlines the proposal. On the left side is the system as it works now and on the right side are two possible scenarios for limited federation (1 direction or bidirectional)
I’d suggest that beehaw’s concerns could be met with a tool that lets you disable posting or voting from off-instance users unless they meet threshold criteria, whether it be account age or post history or manual approval. That would allow you to keep your content interaction controlled without the nuclear option of complete removal.
The Beehaw mods explicitly said that the defederation was due to lack of good mod tools combined with lack of time to moderate manually, and that they didn’t really want to defederate but didn’t know what else to do.
