Thank you all, and especially to Michael :-)
The offending item that I sent a DMCA on was for the Airstream Trailer. I know someone had also recently reported another one of our cars up, but it was removed by the time I checked.
The Airstream Trailer is part of our Fedoraville collection which we updated in 2011 with a lot of new features, including removable snow caps (very handy if you want to do a winter scene).
For the next week, Mirye Software has this collection on sale at 20% off so that anyone who wants to get on board after this bad experience with Dalmatiner can save a bit:

Last year, someone else posted one of our Steampunk City models on ShareCG, but it was pulled quickly. That was the Opium Den (scroll down on the set page):

Now and then we do giveaways ourselves, but even those are covered by a license. This trailer above was never given away, though its shown up on a few pirate sites.
The only way to really resolve use is to license the models. Our art license (Pro is separate and covers use of the original .max file and expanded useage rights) covers 2d renders and 2d animation for commercial or personal use.
