As someone on kbin.social, I'm not seeing it. I saw a comment in a similar thread saying that moderation done on Kbin doesn't federate to Lemmy instances, and I think that's the culprit here. @ernest (the Kbin dev) is working towards a full release, and I hope that it might fix this issue—or at the very least, that it's dealt with shortly after.
EDIT: Yeah, I looked at @science from lemmy.ml, and my God is it awful. This really needs to get fixed ASAP.
This week, I've been dealing with cleaning up instances from spam. Several hundred accounts were removed, along with several thousand posts - these were massive operations. It's possible that due to the volume of requests, other federated instances hit rate limits. I see that some of them are still in the queue with a "fail" status. I will gradually resend them after some time. Along with the update of kbin.social and the first release of kbin, new modeartion options will be available, including spam blocking (such as global blocking domains), a new reporting panel for moderators, and improved federation between instances. I will also address abandoned instances and ensure that each one has at least a few active moderators. I know how urgent this issue is, and it's my top priority. I just need a bit more time as Piotr and I are preparing for the update.
It looks like all the spam I've seen are from newly registered accounts. Perhaps this is something you've already considered, but would shutting off registration on kbin.social and pointing people to other instances until things are more manageable help?
Can you also add moderators to those magazines? I volunteered for the science mag, but have not gotten a reply. Active mods will help with your workload too.
For all the time you have to type excuses, you could be smashing the ban button, but you don't. This does not look like a "top priority" from this end. Stop making excuses and just ban the spam accounts. If you have communities without moderation, then close them. You're managing this very poorly.
It's very annoying. All the spam is originating from kbin, too.
It's not even "can easily be overlooked and move on" type spam either, it's things like "hey kid, wanna buy some oxy?" Kbin admins don't seem to be doing shit about it because these spammers keep coming back with new accounts, and I have yet to see a post removed from the kbin side of things.
It's getting to the point that I hope my instance defederates from kbin because it's just full of trash.
There's a bug going on that prevents Kbin moderation from replicating over the fediverse - what happens is they will nuke the threads but it will not reflect across the rest of the federation which is a huge bug. A lot of instances are either blocking their communities en masse to avoid defederating, or just flat out defederating.
Are you sure it's a bug? To me, it sounds like just how it works. This is one reason beehaw is considering leaving the fediverse (and to be honest, I'd be thankful if we did, based on my recent experiences)
