it's all basically self policing... there have been countless reports of images being used for commercial gain without the artist's knowledge and/or consent... heck I have even seen whereby a videocard manufacturer used an image created by the founder of ZBrush/Pixologic...the image was used on the packaging... so... yea, this crap happens, and... unless you catch them in the act it is futile, and even then it all depends on what laws are set into place in which ever countries and how far the arms of justice will extend cross borders to protect your rights (not very far).
