Up until a week ago, TV Tropes had a very handy trope index called Rape Tropes. (Note: all TVT rape trope pages in this article link, ironically, to Google caches.) This page also linked to other iterations of rape tropes in popular culture such as Rape as Backstory, Rape and Switch, Rape as Drama, Rape as Redemption, and other rape tropes common in the pop culture idiom. Today when you access any of these pages, you’re informed, “We do not want a page on this topic. It does not meet our content policy.” Recently on the discussion thread for combining the “Victim falls for Rapist” trope with the “Rape as Stockholm Syndrome” trope under the standard Rape Is Love cliche, Wiki owner and admin Fast Eddie explained that all tropes related to rape had been wiped off the site because it was getting the site “in trouble with Google.” Apparently that meant any trope containing the word “rape” had to go.
recommend reading the full article; it definitely makes a good argument about why this is bad and why TV Tropes is an important resource for media criticism
