Back in 2002 Stockart was actively soliciting copyright infringement leads:

  ...
  All we need is for you to give us enough information 
  to locate the communication which has the illustration(s)
  used out of copyright, and we will take it from there. 
  In return, we will send you 10% of ANY settlement moneys
  we recover. This could amount to thousands of dollars for
  you AND the illustrators, by simply doing what is right!

Also, Jon (the designer) said that there was at least one other designer that had gave into their extortion scheme, and that he would've given in too if not for the community support. To me this puts the whole situation in a completely different light. It makes it seem as if the copyright "enforcement" is a part of StockArts business plan.
