Hey, good luck to everyone, and super big kudos to OP_Not_Found for doing this!
Uh, let's go with Yuppie Psycho.
I've always enjoyed roguelikes but never really been able to spend a lot of time with a single one until Risk of Rain. It's my absolute go-to.
Personally, I think the Reddit megathread should be updated to strictly link here.
I understand your why, but in the end, I think defederation is probably going to do more harm than good. Lemmy.world and beehaw are both large instances, and for a whole group on one, a non-negligible amount of content just disappeared. Sure, they could just make new accounts somewhere else, but there's no way all of them will. For those that won't, the whole of Lemmy just got a lot less valuable.
I think that ultimately, large amounts of defederation, or just large instances defederation each other, is going to harm Lemmy and the fediverse as a whole. More people might migrate to smaller instances. Some will collapse under the strain, some might become big, follow the cycle and sew more division within the fediverse. A lot of people will get tired of juggling accounts and return to more toxic, but easier, centralized alternatives.
Of course, just not defederating anything isn't a solution either. Well, I mean, it is in a technical sense, but it doesn't get to the root of the issue. My best idea would be some solution that allows users of certain instances to still see content and subscribe to communities, but limit their ability to interact. Think something like sliding defederation. Admins would be able to set what users of specific instances can and can't do, from voting, commenting, submitting down to total defederation for the most extreme cases.
Of course, the best code I've managed myself is a semi-functional python module, so...
