Ouch, what a bug. I knew some of the moderation wasn't being federated, but I can't imagine how a kbin user isn't seeing the latest version.
To be clear, you see the spam when logged in, then don't see it logged out, then see it again when logged in again?
I don't see it regardless of whether I'm logged in or not. Also, I don't think I've ever been able to see it because I don't see the posts in a quick look through the moderation log.
Would you mind posting an issue about this? https://codeberg.org/Kbin/kbin-core/issues Or, I can do it if you don't feel like it and don't mind me using your screenshots. If you do post it, just please emphasize that this makes it impossible for moderation to happen because the moderator literally cannot see the posts.
Thanks again for trying things out and sharing your info!
