I am the author, it's just those 3 terms for the tSNE cluster. Sorry, I can tell from some of the comments here the graphs need to be clearer. "Stepsis" is indicative of incest IMO, the "step" is a fig leaf.
I agree “stepsis” is indicative of incest, but I don’t agree “stepsis” is indicative of violence. And if you’re only using 3 words for “sexual violence”, then why did you go with “incest” instead of “rough”? Those are vastly different kinds of pornography.
