Well even if you were to download the thing and realize it wont work with current releases, you would still be stuck with the fact that anything you made would be subject to what ever laws that are in effect.
So if you were to make a lot of money you should be prepared to loose most if not all of it.
Plus you have to think about how easy it is to track that kind of stuff.
For example you would have to be an idiot to use your forum name when you uploaded to tpb.
I mean I hope nobody is that stupid.
