"as I understand it", we hold artistic copyright whether noted on the image or not. The proof would be in the pudding..all the mess after cleanup if a case were to be pursued..I am posting from memory and an certainly not a legal authority. That is my understanding. If a copyright were to be registered for an image, certainly that would be done in the real name. I am not certain the addition of or name to an image here has any bearing whatsoever on the artistic copyright. It appears more of a "warning" to image hijackers than anything else, but do they care? Who chases after them? Many images which are copyrighted do not necessarily have a signature attached, yet the copyright is valid.
