He has been submitting recoloured images to this group. With recoloured images, you still need permission of the original artist to post them. Without that, it is considered theft. Listed below are his and the original.
His: Original: wallpaperswide.com/sunset_anim… scottpilgrim.wikia.com/wiki/Fi… images4.fanpop.com/image/photo… amdev.ru/wp-content/gallery/my… www.wallmay.net/thumbnails/det… urban-rivals.wikia.com/wiki/Na… en.wikipedia.org/wiki/Hohenzol…
The last few, all he did was cut out the copyright information and change the text. Those also are submitted to this group.
And so on. He has also posted a bunch of screenshots, which deviantART has frowned up in the past.
This is what deviantART has to say about its copyright policies:
--In most cases it does not matter how much of the material you have used. Whether it's a single frame, a few moments of audio, a short clip of video or any other sampling it's still considered to be copyrighted and you still require the owner's permission for use.
--It doesn't matter how you obtained the material, it's still considered copyrighted and you still need permission.
--It doesn't matter whether or not you've credited the proper owner, it's still considered copyrighted and you still need permission.
--It doesn't matter if you are not selling it or making a profit, it's still considered copyrighted and you still need permission.
--It doesn't matter if you can find other people using things without permission, it's still considered copyrighted and you still need permission.
--It doesn't matter if you've edited it a little bit or made a few alterations, if it's recognizable it's still considered copyrighted and you still need permission.

The best way to get these images removed is to go to the image and report it. If you try saying anything to him, he'll target your gallery (even if it consists of things you drew) and say that it's worse than his and that he wasn't destroying copyright but that you are by making fanart of something. He will then block you and hide all the comments.
