I was randomly clicking around DA, when I noticed this deviant in some peoples' galleries:
http://boobapalooza.deviantart.com/
Now, I ALSO noticed that Zdemian's gallery is down, and that
several of this deviant's pictures are moreorless black and white or recolored version of zdemian's artwork, with very slight changes.
Now, I'm not sure how to go about reporting this person, considering Zdemian's stuff is the only notable stuff that I directly recognize. If anyone recognizes other pictures by this person as their or anyone else's artwork, let me know so I can properly report him.
