Oh boy, Kings Folly is on it as well. I hate it when people do that.
But yes, it will probably be on the individual artist for now. I am against bullying, but I would not mind sending a mob of fans over there to leave comments on the website and force it to pull down a little more of their stolen art.
We need to notify the authors, since most of the ones you listed are not active on the forums. I will send a quick message to some of the authors, feel free to do the same.
Edit: I sent a link to this forum post to the creators of Kings Folly and Strays, now I unfortunately have to get ready for work. Get the word out to the rest!
