I've heard kbin.social is having issues since the creator has needed to step away due to personal reasons. It might be best to find an mbin instance to migrate to.
I think it's one particular community on Kbin. I know that if that kind of stuff came into the community that I moderate, it would not last very long because I would murder it.
I haven't been on kbin, but I personally haven't had that issue on Lemmy.
@NotTheOnlyGamer@kbin.social It's a Kbin.social issue, signups are a bit too open and moderation cannot keep up. :/
It’s just Kbin and I hate it 🙂 Kbin has 10x more spam than Lemmy due to poor moderation.
