Freebies were being ripped,  retextured and sold in different markets.  The Princeton library was started because of this.  http://shape.cs.princeton.edu/search.html.  In hopes of keeping track of the anonymous models.  See,  some people weren't aware that they should place their name and a copyright tag on their models.  They thought they were just sharing modeling techniques through their uploads.  No one imagined anybody would do this in an art community.  And, everyone held 3DCafe responsible and pulled their freebies until 3DCafe tracks down all the ripped models.
