I joined about 9 of them last night. In this group:
TranquilTubesAndGraphics
I found an image from Renderosity by Bubba, posted by someone with the yahoo handle of "webwalking1". I IM'd Bubba but I don't know if he's active much anymore so if anyone knows him maybe flip him an email?

You know what is needed is simply for several to join and just police the groups. Some do know what they are doing is wrong but I'm willing to bet a lot really don't realize. If several of us can patrol the groups and inform the artists of the violations we can hit the individuals and perhaps spread a bit of education. The website, www.rightsforartists.com, has sample letters you can copy word for word to send to violators.
