Well, honestly, it's hard to answer anything other than the internet, that wonderful/awful contrivance that has interconnected us all. It's funny that the internet can manage to at once be the greatest and most awful invention of the past 26 years, as the same invention that allowed us to keep in touch with friends, connect with strangers, find answers to questions and manage our lives has also bred deviance to a frightening degree. This invention allows you to find a new restaurant, the menu, location, hours and reviews, but also allows the guy down the street who's curious about Japanese fetish porn to track down the most insane shit out there without too much credit. No other invention has contributed as much to the troubling sexualization of everything, which is probably the worst development of the past 20 years.
