If you're going to start censoring/removing content then why even have a doujinshi/porn upload option anyways? Not only do you have to opt into seeing it, checking recent uploads often features multiple doujins of girls getting raped or worse. And if you're going to say that you're removing content because of "legality" then I'm sure content depicting that would be illegal, never mind any homosexual content in some portions of the world.
You start giving an inch then you'll have to start giving a mile. Pull down all the manwha, Yuri, Yaoi, better aim for some of the standard shonen and stuff too because a gag penis joke or panty flash might make someone uncomfortable.
Oh wait, these are literally drawings and normal people can tell the difference between a drawing and real life, and if you can't then you shouldn't be here anyways.
