If a group is infringing copyright, try sending a DMCA complaint to Yahoo. I did this when a group owner posted one of my articles on his group and refused to remove it.

Yahoo deleted the article, but the group owner left the article on his own personal website, along with references to the fact that he had originally distributed my article through Yahoo. After I pointed this out to Yahoo twice, Yahoo deleted the entire group. (Yahoo probably had received other complaints about this group, as many of the posts were nothing more than copyrighted articles from other sites.)

My point is that the DMCA gives you a lot of power to enforce your copyrights, and although Yahoo is amazingly difficult to contact and very unresponsive, if you are persistent you may get results on copyright issues.
