I did switch that—it's not clear if those three words are the only 3 words defining the category. I suspect not, however, because:
1. It then wouldn't include the word "rough", which is far more common and indicative of sexual violence.
2. Elsewhere the page, the author includes "stepsis" as indicative of incest:
> Later titles are longer, and we start to observe a trend towards both incest ("Daughter", "Stepsis") and violence ("HARD FUCKING", "Fucked ROUGH", "Rough Fuck").
That last quote makes me think that the categories are larger than the 3 examples given, and "sexual violence" includes both the incest and violence terms.
