PieFed has this in the admin area:
So admins don't need to stay on top of the latest defederation drama, just choose who to outsource that work to. From that baseline you can add more defederations manually.

Came for the 'should degenerate'
I done defederate. Seems censorship and contrary to the concept of the fediverse.
But I also run my one user instance, so well...
How do you stop really nasty stuff from getting to your instance?
(I know nothing about how and when fediverse transfers data)
Since I am on a single user instance, the instance receives only stuff from the communities I subscribe to.
This means that I just select what I am interested in.
So far after over 1 year I never seen a single "dangerous" piece of stuff, so I think the risk is a bit overstated.
The downside is that my "all/everything" feed is identical to my subscribed feed, bummer.
As someone who also runs a single user instance, lemmy uses the protocol activitupub, and the way I federate my server is auto federate with any instance federated by piefed.social bc I like rimu@piefed.social ethics.
None. I don't have any blocked and it's been fine.
What does it mean to defederate?
It's like federating, but not.
Thanks for coming to my TED Talk.
I jest.
A lot of people compare the fediverse to email domains. bob@outlook.com can talk to sally@gmail.com - no issues.
Imagine if there was an email service made by Jeffrey Epstein, for him and his buddies; LolitaMail.
It should go without saying every email service should block all LolitaMail communications.
That's what defederating is.
I thought federalization was about not having an owner of a platform. Decentralization. I have some reading to do
The federation is community owned (which is why you see so many communists here).
Lemmy itself is not a single instance, it's merely the technical development of the platform itself.
You are a user of the sh.itjust.works domain, who is owned by a real person.
There are bad Lemmy instances you don't want to be part of, and the owner of sh.itjust.works has blocked that instance, you'll never even know it was there.
There is no single author of a list of instances which are defederared, but many instances simply piggyback off the blocklist another instance uses (lemmy.world for example).
not really, every Lemmy instance has an owner...
What federation is is that every Lemmy instance gets some of its data not just from its users, but also from other Lemmy instances. You can think of each Lemmy instance as one mini-reddit, in principle there is no difference between reddit and one single Lemmy instance. Federation means that Lemmy instances copy their data from/to each other so that you can talk to users who use other ones too.
So defederation just means we block some of instances
Ah so it’s about moving away from Lemmy and back to Reddit for example?
