I see a post here: https://lemmy.ca/post/921003. There is only one comment from me, but on lemmy.ml there are more comments and votes. Why is this the case?
I’ve found this in particular with lemmy.world with posts made on lemmy.ml communities, which seems to be the case in your example as well (the community you posted to is ThinkPad@lemmy.ml).
Lemmy.world has been defederated in at least one high profile case. I have a suspicion .ml may have defederated as well without announcing (unless maybe we have defederated them here @lemmy.ca? Still working out how source of truth works myself). edit: checked, both still list .world as linked
If an instance defederates another it means they will not accept engagement from that instance. However, if that instance does not reciprocate the defederation they still get a copy, and it is isolated to their instance. Ie. Comments/votes only appear on that instance and the instances they federate with.
Not entirely sure though as I would think that means lemmy.world would still receive edit/deletion broadcasts which it doesn’t from my experience. So maybe just a bug.
Basically, at least from my experiments, Lemmy.world gets the original post / comment, and all engagement on the lemmy.world instance stays isolated there (lemmy.world has a large user base therefore often more engagement).
This is going to be an ongoing problem for folks because there really isn’t a way to see who (instance) is talking to who (instance) (edit: incorrect; a user pointed out a place to check, but it isn’t always going to be clear unless you constantly check). Without a platform wide policy of mutual, reciprocal defederation, there is going to be a lot of fractured discussion users will never be notified of.
*edit: may not be an issue with defed. See comment below.
This page shows which instances we have blocked: https://lemmy.ca/instances
I think that part is still up to the instance to announce. In the case here at lemmy.ca the admin has made a call to block those on a list another admin has made of problematic instances (seem to be primarily instances that have seen a recent, unexplained spike). Note this is not the issue with Lemmy.world which is not blocked, the issue with them just seems to be either overloaded or general issues with Lemmy or .world right now.
Difference in signup policy creating moderation overhead the reason for the high profile case:
Oh sweet. That is way easier than what I just did. Updated my comment on not knowing.
Yup, that’s the issue. Thanks!
Err. Actually didn’t read column headers. It says linked, so maybe a version issue / some other bug.
Definitely not working from .world as I posted from an account there on this thread and it hasn’t shown up. I haven’t experienced this with any other instance yet, just .world
There is a sailing community I engage with that is straight Lemmy.ca to Lemmy.world. Seems I get some federation but not all, so probably not a defed issue.
Lemmy.world appears to be running out of date version of Lemmy (boo lemmy.world)
Our admin might just be too on top of things for them to keep up.
*edit: or maybe it is defed https://lemmy.ca/post/919062.
*edit 2: Seems to be, I just tested on this thread from a .world account.
*edit 3: not defed, just .world probably being hammered along with other Lemmy growing pains.
I doubt that it’s defederated because of the bot count. I ran into the issue (Lemmy.ca <-> Lemmy.world) already well before the bot invasion
The list says non-comprehensive, but with an instance as large as lemmy.world, you’d expect it to be listed, if it would be defederated. Plus Lemmy.world is still listed on linked instances.
There must be a different reason for the poor synchronization between the two instances
Edit: See comment further down. Smorks is aware of the issue and will look into it.
