The guy that manages Kbin has been having personal issues and stepped away from the fediverse so yeah Kbin is kind of in limbo at the moment and indeed not well moderated. There’s mods but there’s just so much they can do. The software doesn’t federate the deletions so even if they’re gone on Kbin, they remain everywhere else.
Kbin /m/fediverse is over 90% spam (kbin.social)
Looking at the front page of this forum and many others, leads me to conclude that kbin has a ridiculous spam problem....
