The problem is that Kbin sucks as well. For example, /m/science lacks actual moderators and gets flooded with spam on the regular. And even where there are active moderators, moderation actions often do not get federated.
I was hoping these issues would get fixed soon, but here we are, three months after the Reddit apocalypse, and Kbin is still not a fully functional platform. For example, I filed bug #1102 fifteen days ago, and this has still not been resolved. And bug #570 has been open since early July.
If Kbin wants to become and stay relevant, it needs more hands on deck.
