It’s a recurring issue and has been for weeks now. The most recent one I noticed was this comment, which despite being tagged 4 days ago, only just recently appeared in my inbox.
A while ago it was only 2 days, but the problem seems to be getting worse and worse. In a meta post on my instance, an admin noted that they don’t believe it’s anything they can resolve on their end, so I’m posting here on the assumption that it must be a LW issue.
I think you’re thinking of a post about another instance that was misconfigured and causing .world to send out duplicate updates to other instances, hence the block. I thought it was an announcement, but I don’t see it in c/support now.
Edit: I found the post - https://lemmy.world/post/14183949
Oh no, poor Ernst is at it again! He needs to be more careful, when his actions affect people all over the world and all the more so beyond his own server:-(.
Thank you for finding and sharing the link! I actually was thinking of an entirely different instance (I think) that was noticing the duplicates, but perhaps the issue with Kbin.social & Kbin.earth was somehow the real underlying culprit, and anyway a post with real information is much more preferable to read than rambling half recollections of what might have been:-).
