A refugee from reddit like a lot of others I guess. I registered to .world because it was open and .ml was kinda full. Now as the dust of mass migration starts to settle the leanings of different lemmy instances are becoming clearer. The fact that lemmygrad is just straight out batshit /r/Donald was pretty obvious right away. The fact that .ml passes downvotes to the CCP social score system was not. Federation starts to dissolve into islands of let's call them "interests". Two questions come to mind:
Is there an overview of what instance is federated with what instance? A reason for defederation would be nice too.
Is there one place where I can check moderation policy for this particular instance? Two of the instances I came across turned out to have "leanings" as already mentioned. May I cautiously ask what "leaning" if applicable I might encounter here?
Here is the list of all instances federated or blocked by lemmy.world. I couldn't see defederation or blocking instances in the modlog so there might not be a log with reasons.
As for rules. I'm just checking what each server a given community is on. Most things are only on a handful or instances. If a community keeps popping up on a feed from a community on a server I don't like, I just block the community. I'll probably keep doing that until user level blocking of instances is implemented.
Do you know if there is a way to block instances from a community you have created? I made [email protected] and I'd like to block the entirety of lemmygrad's crazy assholes from my community.
I don't think there is a way native to Lemmy for a mod to do that. You would have to talk to the instance admin you are on to defederate them at the moment. This might change in the future.
What you might be able to do is see if anyone has made a mod bot yet. Then you could configure the bot to ban anyone who posts from instances you don't like. So reactive bans instead of preemptive.
I've seen the first couple bots pop up so I would expect to see a mod bot pretty soon.
As far as I'm aware defederation is one way. If instance 1 defederates instance 2 it means they won't accept posts, comments or any other data from the instance 2. But instance 2 is still capable of viewing the data from instances 1 much like an unlogged in user
Looking at lemmy.ml/instances I dont see lemmy.world in the blocked list. I don't think either has defederates the other. Are you thinking of Beehaw?
Mastodon instances are technically able to interact with lemmy instances. Both platforms use the ActivityPub protocol. The issue for your average user is the UI frontend of the platforms don't have anyway of doing the correct queries or display the information from each other. But if you use alternative interfaces, I think it's basically just all command line utilities at the moment, you can view content and post across them. There should be some other platforms able to do this as well.
I remember reading a post on lemmy.ml today where several instances have been defederated for "loose registration process". Lemmy.world was among them. But of course I can't find it again, so I might have gotten something wrong or just someone posting BS.
I feel a bit more reassured that I am safe here. I will check out the CLI tools for ActivityPub, thank you for pointing me in this direction.
Someone mentioned to check out what admins are writing about themselves, what communities they are in to get a gist of a possible leaning of an instance. That turned out to be a helpful tip if you check out the lemmy.ml admins.
