Since you asked if it was something outside of possibly copyright, I would suggest more funding for artists in the first place so that they don't have to be working a bunch of other jobs and can maybe be more informed and spend more time being aware of their rights and protecting their work. That would probably help things out in a very general way. I realize it's not getting at the heart of things, but in general, artists get really tied up and can't necessarily devote enough time and space to protecting their craft.
