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.
Kbin.run was running mbin too
Yea in fact kbin.run was run by debounced. A very beloved mbin maintainer, if I say so myself.
