I saw Scan's, which says under "Pixiv" and pixiv is a page style Deviantart.
ajkk upload images from Piviv, and the original author does not know.
Example:
ajkk upload:
Vocaloid#461898
this Scan is from: http://www.pixiv.net/member_illust.php?mode=medium&illust_id=2784211
therefore, ajkk upload to MT without permission of the author of Pixiv.
