As you have probably noticed, I renamed old boards. More specifically, renamed "Hentai" to "2D Ero", "Lolicon" to "2D Lolikon", and just now, "Anime/Cute" to "2D Cute". I found teh reason important enough to make a thread about.
The reason is simple: To get rid of ancient Western misunderstandings on this site. Yah, we on Heyuri are too elite to make such mistakes

"Hentai"（変態）is a Japanese word meaning something like "pervert". Japanese people refer animated R-18 rated anime as "eroanime"*, their source manga as "eromanga"*, and if they are doujin works, "ero doujinshi"*. Erotic images are called "ero gazou", if they are 2D characters then "nijigen ero gazou" and so on.
*Japanese language doesn't have spaces so it can be as well "ero anime" etc

Not all 2D girls are "Anime girls", this is an extremely often made mistake in the West since probably long ago. Japanese people always call them 2D girls. If the 2D girl happens to be from an anime series, they would then be "a girl from an anime" (and even then, you wouldn't find any result for "アニメ少女" at all instead of "二次元少女")- but for example, OS-tan girls aren't from an anime so they are just 2D girls. Thus I renamed Anime/Cute to 2D Cute.

As for 2D lolikon (Japanese is rorikon but granted, they just don't have c and l letters. I write it as Lolikon as stylish choice.), Japanese word refers people who have a loli (rori) complex - of all dimensions, primarily 3D when spoken IRL. Thus it's important to specify they are 2D girls.
Similar case with guro. Japanese word comes from grotesque, and refers to disgusting things from all dimensions, let it be blood or shit (or bugs - look up グロ虫 if you dare). So, while I didn't add it, proper title for a guro board would be "2D Guro".

I didn't change Anime/Manga since they actually refer to アニメ and 漫画 here ヽ(´ー｀)ノ
