I'm coming to you with this small article to make you understand why you should google your artwork...
Here's the story...
Today while eating my lunch at work, browsing the web like i'm used to do during those small 10mins of break, I found one of my artwork on a facebook link...
Strangely this was a spanish "zen" website...
So I've Google this image and find out that this exact same picture was used ... for a CD !
By searching, I've finally find the "art association" created by the "designer" itself and finally find that this exact same designer used deviantART's images to create is own "artwork" and sell them for everything ... Like a full wall print in a restaurant, CD, t shirt, flyers etc...
As another example I've recognized this particular fractal but I can't remember in which deviant's gallery I've already seen it ...
I've also seen some photomanipulation which could come from deviantART ...
