lemmit.online is currently allowed on sh.itjust.works but blocked on lemmy.ca so I looked into it a bit deeper and found there are other differences between the list of sitewide blocked instances for each server.

I'm bringing this to your attention as a low priority background task request to review the differences and see whether the instance in question should be blocked on both sites or allowed for each since they are both fedecan sites.

Here are some stats about the blocked instances:

  • 90 instances are blocked on lemmy.ca
  • 100 instances are blocked on sh.itjust.works
  • 29 blocked instances are common between lemmy.ca and sh.itjust.works
  • 61 instances are blocked only for lemmy.ca but not on sh.itjust.works
  • 71 instances are blocked only for sh.itjust.works but not on lemmy.ca

I'll post in some comments to this post the list of instances blocked on only one of the two fedecan owned lemmy servers and the shell commands I used to gather the data.

That is correct :) As of right now, the plan is to keep the federation policy separated at the instance level. There are some subtle differences in the current draft of those policies

Some of the instances in the list are obvious spam/scams that no one wants to see, and sh.it just.works might defederate away from those ones easily. We have only started working together somewhat recently, and its likely that many instances in this category just never federated over to them, or they have already shut down.

For others they will need to raise a discussion with their users to see if that is something the users want. I think it is healthy for there to be some differences in the overall federation lists, since then users can choose which experience is right for them.

Also tagging @SomethingWentWrong@lemmy.ca, thank you for doing the work and sharing those lists / the script. We haven't had a chance to do this kind of analysis yet. Another advantage of listing the federation decisions is that users can compare instances when deciding where to make an account.
