Hmm, sounds like the park has started to contact sites about the issue and is getting people to take down the images. They won't get all of them, but they probably want to keep it as contained as possible for the GP's sake. Unfortunately, the GP isn't as shielded from the enthusiast world as they once were. Earlier today someone posted a link to this very thread on SDC's facebook and we got a big spike in traffic, and people have been posting the layout all over tumblr and faceboook as well.
I don't know what we can do about it, but do what you can to keep it on the down-low as much as possible I guess. I don't know what that means at this point either. I hope we weren't the source of the "outbreak" as it were, I don't see where else the link was posted originally. We'll probably have to make some formal rules about this for the future.
