I had noticed that some cross-posted posts showed a different style of link for those cross-posts: some show it as a link under the title and header of the post but above the body, and some show the link (usually) in the body of the post. In addition, the cross-post links above the body are relative links (open in my home instance), but the ones inside the body are hard links (open in the source community’s home instance). Lastly, the links inside the body show only on one of the cross-posts, but the ones outside the body show on both cross-posts.
At first I thought that the second style, the one in the body that’s hard-linked and only on one of the posts, was due to the poster manually adding that link. However, over time I realized that that was not the case because it looked too consistent across different users.
I searched for a mention of this in this community and found this post about it: https://lemmy.zip/post/8016049 - unfortunately, there’s either something I’m still missing or that the explanation is missing.
Here’s an example post I happened to find that is linking to an external article’s URL, but has both styles of cross-post link. It’s a post linking to an article URL too: https://sh.itjust.works/post/64304718

Does anyone know how or why the two different styles of cross-post link get created?

the hard link in the body text is generated when there is body text in the original post
But the original post in the screenshot in the OP has no body text and yet has the hard-link in the body? Thanks for trying to help me understand, but I’m still not seeing the pattern.
It was edited in or written manually, the user can do it by hand if they wish
unless they’re using a weird frontend, it wouldn’t do that
I had thought manually added for a long time too, but then lately I’ve realized that the pattern is too perfectly consistent, across multiple users.
I’m leaning towards a weird front-end or app too, something that maybe implemented cross-posting before Lemmy’s native functionality. One clue I’ve received from someone who posted something like that is that they used Alexandrite, but I don’t have access to that to do some testing.
