Alright, that's it. If someone can make money out of most likely tracing pictures, and copying other people's art (and calling the design "their own"), then I sure as heck can make money out of my own art done fair and square. 
I've always been so uncertain if my art would sell or not, but the fact that someone so ignorant, and blocks you whenever you try to point out they are breaking the law, can do it and get away with it just fuels my fire to open up commissions and strife to do it better and do it based all on my own skill.
