Torley,
Fade Languish told me you're the best person to contact for this. We ran a controlled test to see how bad the texture theft by eyedropper issue is. Results: Very bad. No texture that is put on an object is safe.
I do not want to disclose the complete details of the method publicly (though I think you can figure it out too). Can you give me a means by which I can communicate to you the details of the technique so you can assess how bad the situation is?
This link shows the stone wall of the Archer House (newbie item). This texture is ripped directly off a copy of the house that isn't mine. Compare this image to your originals on file.

I am personally not affected by this problem because my work is not heavily dependent on texture rights. But I foresee a very bad problem, potentially explosive, if this is not addressed quickly.
