For sure! I think most of them should be perfectly fine for Kbin communities. I don’t even notice the difference when I interact with the Kbin ones. I assume there may be some federation issues so maybe I’m not seeing all the Kbin content, but I can’t tell otherwise
You can for sure advertise it in !communityPromo because it’s open to communities on any platform (source: me because I wrote that guideline 😄)
