I'd like a client side feature that groups all the community that have the same link posted together.
The best example I can think of as to why I want this was the day musk did the salute. Doomscrolling was just that twats imagine was fruitless and I had to put poor lemmy to bed early that day.
If you post a link, that’s already been posted in another community, it shows the post as cross-posted.
I am talking about posts in the same community.
I believe that detection works for posts in the same community too. I posted two same links in a community and both was detected as cross-posted:
You can get the cross posts via API resposne. See cross_posts field in the response of https://<instance>/api/v3/post?id=<ID>.
Sadly, it does not show in Jerboa for Android.
Here's the relevant issue: https://github.com/LemmyNet/jerboa/issues/1666
This could be a great moderation tool. Have you found anything related on GitHub?
Nope.
From what I've read, it's been deemed quite expensive and so it's not feasible within the current database design.
Fairly sure that this is never going to happen, nor do I think it should, unless you're describing duplicate content sent to the same community on the same instance within a certain period.
The fediverse is decentralized and by design each instance is independent. Data is shared between instances depending on subscribers. There isn't a central database for every post or comment.
A person posting the same content on two instances would each automatically distribute that to other instances. At some point there'd be overlap when the duplicate content arrived at the same instance.
At that point, which one is duplicate and which one is original? Do you delete the duplicate? What about the other instances that already have the content?
Do you want to introduce a definitive source of truth that tracks which post was first? Doing so creates a single point of censorship and failure.
So, I'm going with, no, that's not something I think can, or should ever happen.
I mean if the same community have the same link in 2 posts, the second one should be detected and deleted.
In that case the second poster should know that this is a deplucate link so they would not post it.
Most communities allow editorializing in the post anyway, so not sure that it would be that let straightforward. i.e., someone is posting their opinion on something and they also give a link to a related article.
It would be trivially easy to create an automoderator bot for that.
What app are you using? The regular Lemmy-UI already does this. In fact I have a feature request asking to be able to disable it...
Jerboa, if I tried posting a duplicate link into a community, the client will accept it, without even showing a warning.
Yeah it depends on the app, they don't all do it. Boost shows cross posts, but doesn't merge them.
