YSK: You can see which instances your home instance is federated with and which they've defederated/blocked by going to "/instances"
For example, you can see this breakdown for Lemmy.world by going to https://lemmy.world/instances
That list won't show which instances have block the home instance. The blocked list lists only the instances the home instance has blocked, not the other way around.
How does this work exactly? If another instance blocks lemmy.world for example can I still see (but not interact with) content on the other instance, or is it completely invisible?
Basically it works like this:
Instances A, B, and C are federated initially. When a user posts on Instance A, users on Instances B & C can see and interact with the post directly. Any comments they make will be sent back to Instance A as the "home" instance for that content.
Now let's say Instance A decides they don't care for the type of interaction they're getting from Instance C's users and decides to block - or defederate - Instance C.
To users on instance A, nothing changes other than new posts and comments from users on Instance C will no longer show up. To users on Instance B, nothing changes other than new comments from users on Instance C won't appear in posts they interact with on Instance A. However, for Instance C, things are suddenly branched.
On Instance C, any posts that were created prior to defederation still exist in Instance C's record. However, any comments that users on Instance C commit to those posts will no longer be distributed to users on Instances A or B, because Instance A maintains the "primary" record of the post. Similarly, Instance C's users will not receive updated comments from users on Instance A OR Instance B, because again, Instance A is what determines which comments appear in federated instances. Furthermore, new posts created on Instance A will no longer show up in users' feeds on Instance C. From the moment of defederation, Instance C's copies of all posts on Instance A are now distinct, and the only new comments or updates they will receive will be from local users on Instance C.
I don't know if an instance has an active way to know some other has defederated from it.
You can view which instances blocked lemmy.world (as an example but any lemmy based instance works and others may work too) on this site using the field below "Enter a Domain"
The link is also down at the bottom (at least in mobile version}.
I've been lookin at some block lists just earlier today. I have to fess that some instances' block lists make me uncomfortable.
Ah didn't even notice it at the bottom, good catch!
What makes those block lists uncomfortable for you, genuinely curious?
First, because some instance's block list indicates unwillingness to see anything beyond their little world.
Second, because in some (only only some) blocklists, there are links to some actual shitty people who I wouldn't think actually have the capacity to run a server.
In the last few days there's been quite a fuss about some instances storing insulting jokes and whatnot, but maaaan that's honestly nothing compared to what else is out there.
Funny finding skinheads.social on that list there. Is federating automatic, requiring an opt-out to separate, or did an administrator see that name and go “yup, we want people to see skinhead content?”
Federation is automatic unless your instance is using a whitelist setup.
If I understand it right, federation happens automatically when someone from a new instance interacts with the home instance, or someone from the home instance searches out the new instance.
It looks like that site might be running with the British use of "skinhead" and not the U$ use. It was a progressive punk/ska subculture before it became used as a white supremacist thing in the U$.
I haven't looked at that instance but can corroborate that there are two very different groups called skinheads who's philosophy's are entirely incompatible with one another so it is always important to clear up which one you're dealing with.
I don’t mean to repost a comment, but I’m looking for context. Are skinheads common in Germany? They seem to have a fascination with German culture over there.
In Europe we have red skins (leftists) and apolitical skins, so being a skinhead is not equivalent to being a nazi (although we also have naziskins unfortunately)
Are skinheads common in Germany? I checked out their instance the other day and found them speaking quite a bit about German culture. Now I’m not saying all Germans are nazis by any stretch, but nazis do have a fascination with Germany.
That’s a lot of instances.
Is there anything like this for kbin?
Couldn't find any info on this. Curious too
Can't find anything like that on kbin but it would be super handy to have that somewhere accessible (maybe in the footer). I'll ask the dev chat
You can use this sites reverse search function as well, but I do not know of an alternative for kbin
Not implemented yet.
This is so helpful! Thank you!
