Recently, I’ve noticed federated threads/comments/votes were lagging behind, and it turns out kbin.earth was being spammed (hundreds in a minute, leading to a couple thousand queued messages after only half an hour) by a Lemmy server with the same exact activity pub message. After blocking the server (feddit.de), federation should now work correctly. If the admins of the server ever fix the issue, I’ll be glad to unblock it.
Edit: turns out, this was probably actually a kbin issue, but at least it’s fixed the issues temporarily.
Hello, thanks for reaching out. I wondered if the federation issue we’ve had was actually just a kbin issue, but it’s a lot easier to see incoming messages than outgoing, and I just assumed it was feddit.de’s fault when I saw all the spam. Unfortunately, I’m guessing I won’t be able to do much to fix this since I’m not a kbin (or php) developer, and Ernest doesn’t seem to be actively developing anything (including bug fixes) for kbin right now. I’ll message you on Matrix for more details, just in case.
