Ah, okay, it's on 4chan. There's a really, really fast moving Stable Diffusion thread in /g/ that runs to the bump limit and is recreated every hour or so. They're telling me that any furry related stuff is in a containment thread in /trash/ instead. Since I don't have the hardware needed to run a local instance I am not sure there's much to be gained from a deep dive there.
I am not sure myself. I'm scared to look. They say it's an "Internet hate machine" filled with "hackers on steroids."
