The Community Guidelines (which are part of the ToU) say "Don't post porn, shock images, or explicit descriptions of sex" and "For text, content that just mentions characters have sex is likely to be OK. But content that describes exactly how they have sex, is not. Content that describes violent or non-consensual sex is expressly prohibited."
This wiki contains content that includes rape, underage sex and beastiality. This content has to go.
I will remove the obvious pages, but you will need to look for more areas where rape and teen sex are mentioned, and remove them from this wiki. You also need to check for other overly explicit content, including any that describes sex in detail.
I'm sorry that I have to be strict on this, but even wikis on adult topics need to abide by the ToU.
