Is it possible to de-duplicate lemmy posts from other instances? (sh.itjust.works)

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?

There are no "actual" cross posts. Cross-posts on Lemmy are just all posts that have the exact same URL in the URL field.

So if I post a URL to one community and post a URL of that post in another what's that?

Not a cross post. It just creates a post that links to the first post.

If you made a third post that also linked to the first post using the same url as the second post, that would be detected and get linked up as a cross-post to the second post.

Actual cross-posts work in both directions. Lemmy detects them as the same thing, both posts link to the other.

Not in the post body, the post body quote and "cross-posted from" text is completely meaningless and just gets added by most clients, adding it doesn't make something a cross-post, and removing it doesn't break the actual cross-post feature, which shows up as a little "cross-posted to: list of communities" thing on the post page.

Thunder has it, Photon does it, and the default webUI does it.

So does that mean shared comments? Or are they separate? And yeah I'm on eternity hangover from the Reddit days.

No, the posts are separate. But each post will list every other post so you can visit the other comment sections.
