From this post (https://sopuli.xyz/post/15865566) on !AskMbin@fedia.io
It’s very likely related, but we also figured out that both of debounced’s (the admin of kbin.run) accounts on GitHub and Matrix were deleted last night. So there is a possibility that kbin.run is no more.
I actually miss the microblog integration on vanilla kbin, but I don’t think we’ll ever get that back.
I might just finally give up and settle on lemmy. There are a lot of really good apps for it these days.
