Status

How these links should work? They always give me "server error". User:2001:9E8:1844:F100:EC3D:B6E8:D508:4F42 is massively adding links, but some of them are reverted by User:מקף, can you also comment? Infovarius (talk) 08:20, 16 August 2023 (UTC)

Some of the IP user's additions seem misdirected, e.g: adding a Fox News community link to the fox animal's item page.

The IP user also might be running a bot to add the links.

As for the "Server Error" message, it might be because all these links are going through lemmy.world's "federation interconnect" (tentative name) interface, and sometimes it's a bit unstable, based on the load of lemmy.world. But in all cases, the "federation" interface is displaying a cached version of the community, which might not be up to date with the source community.

You can visit the source community using host.tld/c/communityname, but in case of Kbin (which is NOT a Lemmy community, but an ActivityPub-enabled forum platform), it's kbin.social/m/communityname. Kbin is also a separate forum software, but Kbin-based sites use the /m/communityname format instead of Lemmy's /c/communityname format, but on the federation side, this difference doesn't count.

Also, take into consideration that there are "problematic" instances that host inappropriate material and etc., and those should be placed on a blacklist to make sure they aren't linked from WD.

The foxnews community is actually about foxes foxnews@lemmy.sdf.org – Shisma (talk) 06:59, 17 August 2023 (UTC)

Oh well, then I guess it's like the Superbowl subforum, which was actually about superb owls, not the event. CrystalLemonade (talk) 07:21, 17 August 2023 (UTC)

yep. sorry about that 😅 – Shisma (talk) 19:40, 18 August 2023 (UTC)

Hi, thanks for the ping.
Indeed, I reverted some of his edits because I saw that they were incorrect additions, and I even believed that they might were intended to create cover for the edits in the items abouts decentralized coins, which to me seemed to be spambot edits. · ^מקף Hyphen _෴ · 16:27, 16 August 2023 (UTC)

Only one value?

Hi!

With federation, it's often that a same topic will have several communities on different instances. Off the top of my mind I can think of cooking@lemmy.world, bonnebouffe@jlai.lu, cooking@beehaw.org, food@slrpnk.net, etc. which are all cooking or cooking-adjacent communities.

Would it be possible to remove this constraint? Exilexi (talk) 08:26, 31 October 2023 (UTC)
