Lemmy could do a lot better job of showing that a community is on a dead instance. Here's an issue about warning when posting to defederated instances, which could be considered the same issue: https://github.com/LemmyNet/lemmy-ui/issues/2680
I don't see a way to simply lock it down as an admin. I see "Remove" and "Purge community" which both seem to be too nuclear, I assume they'd delete the comm history too.
I'm pretty sure it's doable but it might be necessary to become a mod first, which admins should be able to in remote communities as well iirc. it's just that their mod actions won't federate.
While scrolling to find my posts on lemmy.film to crosspost elsewhere I checked in on some posts on !startrek@possumpat.io and apparently possumpat.io is shutting down soon to :(
Are there any other instances you know of that’s down for the count?
For a while people were still posting to the lemmy.world copy of synthwave@waveform.social even though waveform.social died. So someone just made a "this community is dead" post.
lemmy.world is the largest Lemmy instance by far and is causing growing concern that it's causing the Lemmy-verse to become too centralized and strangling out smaller instances either intentionally (if .world defed's from your instance you immediately start losing out on a ton of content/traffic) or unintentionally (people just post there by default leaving little content for other instances)
So now there's ongoing efforts to try to balance things out a bit
Lack of updates on LW. At this moment, LW users still can't delete media they uploaded. That was a big deal in March 2024: https://tech.michaelaltfield.net/2024/03/04/lemmy-fediverse-gdpr/. Since then, Lemmy allows it since 0.19.4, but LW still runs 0.19.3 (there are plans to update, but at the moment we're speaking, it's still not the case)
Smaller instances can have issues to keep up with LW due to its size: https://lemm.ee/post/28755787 . Again, those issues were fixed in 0.19.6, but LW is still on 0.19.3.
the site (or at least lemmy.world) is sooo slooow. Basic functions like loading images take me back to the dial-up era of “click the image then do something else while it loads,” which is downright ridiculous in the 2020s. Again I’ve stuck with it because I want to support the fediverse, but 99% of users won’t.
