I'm afraid I don't know any more than anyone else.
Up until recently, I was happily downloading Dalmatiners models when a few other SCG members posted a link to a "free site". On that site was a car that was identical to one that Dalmatiner had just posted as one of his originals. (I don't remember the car, because I didn't download it). It was only then that I started asking Dalmatiner in the comments sections if he was the actual modeller- And what about his 'other' cars?
The thing is, for the SCG people who want to use any of Dalmatiners models commercially - how do you go about proving that they are legal?
Could we ask Dalmatiner for a list of the 'legal' models? My question is- How much credibility does a person have who has just submitted a Meshbox model as his own?
So, until anyone has a solution (still hoping?) I will be removing all Dalmatiner content from my runtime.
