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.

I can tell you one reason for a portion of them on the lemmy.ca exclusive blocks, having been here just a handful of months prior to the Reddit-exodus of June 2023.

Since lemmy.ca is a few years older than sh.itjust.works, there are some servers that were blocked back then, for spammers or trolls that no longer existed by the time sh. first came online. One particularly infamous example from the early Lemmyverse is wolfballs.

Oh and the request/intent to join announcement seemed to indicate that while Fedecan would be an infrastructural and fiscal host for sh., it was agreed the operational management of their Lemmy server would be largely left to the existing people. I suppose no harm in reviewing the differences if there's time to spend, but just trying to provide whatever context I can to your analysis.

Thanks for the context.

Your the request/intent to join link doesn't appear to go where it should be.

Email has been doing the "whack-a-mole" battle with spammers for a long time and have tools like https://www.spamhaus.org/blocklists/ to quickly block the latest bad actor.

The Fediverse will likely need to do something similar in identifying and quickly blocking bad actors.

Sorry bout that, link fixed.

A couple idea threads to pursue in response to your follow ups: Have you seen dbzero's Fediseer? Also, automated community moderation to automatically block users that comment more combatively across other communities and unblock once they establish a pattern of being less so, has been tried on a political news community on lemm.ee before, but lemm.ee is gone now for unrelated reasons. I just wonder if that underlying project is still available and in use somewhere. I don't currently have the energy to look it up.

Ah cool, I wasn't aware of dbzero’s Fediseer. Looks like a good way to identify problematic instances to block.

I'm just an end user of lemmy trying to use it more and went down a rabbit hole about blocked instances when I came across something that impacted me.
