Is it possible to de-duplicate lemmy posts from other instances?
It’s annoying seeing the same headlines numerous times linking to same stuff because it’s cross posted to 3+ instances.
Is there a setting to reduce that or app that handles that well?
The default webUI de-duplicates cross-posts. I don't know if any apps do.
They have to be actual cross posts though, don't they? Would that catch the same link spammed across multiple instances and communities?
Yeah - I think anything the UI is doing, it's getting the info from the API, so the poster would've had to use the 'cross-post' feature. There are some apps (e.g. Voyager) that try to wrangle cross-posts by title or URL, but title-matching can give false postives, and URL-matching usually assumes that one link hasn't picked up some cruft, and it can't do much for uploaded images if the poster didn't cross-post (because it'll be 2 different files with different URLs)
News to me! Good to know. Will have to see how that’s handled and maybe make pr to my favorite apps
If you find any with it let me know. Not hopeful for Sync.
There ought to be a way to tag a single post for multiple communities
I just block the users who do it. Requires a few seconds and then I don't worry about it again.
