Just a heads up
There are several angry pixiv artists on twitter and 2ch that complain about people taking their art without permission, edit them, and sometimes put watermarks on them. Even if they get credit, they didn’t ask for permission. And I’m sure you wouldn’t want your art to be edited, because that gives a negative impression towards the original artwork(Or so some illustrators think)
There was one thread on 2ch that started a small movement to have Pixiv’s regulations, making it only accessible to people inside Asia, until the US site was opened.
Though there are very few people who do ask for permission, even if there’s a language barrier, the illustrators will try to communicate back to the person.
Taking their art and posting, as in “Right click, save, upload” has no harm at all, since the regulations of art on Pixiv explains art in a way that is meant to be expressed visually. and most preferably, it’d be nice if the uploader posts the artist source of the image. Though a big no no is taking the art, editing it in any way, (excluding “Cropping”) and posting them, since that requires specific permission. It’s actually illegal in Japan to do this, and more of a crime to even put water marks. Though these laws don’t apply overseas considering it’s only a minor case within the whole entire political economy of Japan. Japan’s laws on art is much much more complex that regulations within the states or anywhere else in the world, considering how most of the profit comes from Doujin-work, and there are /a lot/ of illustrators in Japan.
The fact is, Japanese illustrators on Pixiv or anywhere else do not like their art to be taken and edited, and put water marks without premission. Even if you asked them, I’m sure they won’t give permission, considering the fact that editing a picture kind of tells the illustrators that “I want to make this art better-looking”(As so they think). I’m sure you wouldn’t want your art to be taken, edited, and posted without permission, with someone standing in the spotlight of the artwork, despite the art has been credited, yet no permission was given.
Pixiv isn’t going to be restricted to overseas, this may be an issue, but there are only a few artists who have the courage to express their anger to the moderators, and the rest just vent and complain on twitter or 2ch.
People that complain that their icons (cropped/edited from fanart from PIXIV) or graphics (cropped/edited from fanart from PIXIV/video from Nico Nico) have been “stolen” when other people use them, but it’s okay for them to be editing to make these said graphics, need to read this.
