If your work is any good it will get pirated. Yes you could watermark it, yes you could probably work out who gave away the first copy. Whether you could, in practical terms, do anything about it is questionable. Would it take up a lot of creative time trying? Certainly. The only thing that stops piracy is one's own personal code of conduct. We are all on the honor system. I'm not giving away any secrets when I say that I can download my entire catalog in an evening from P2P networks. Does that affect the amount of groceries that I can buy at Wall Mark? Yep. Can I do anything about it? Nope. More to the point I do not worry about it I just keep pushing out more stuff. Something that, in my opinion, the bulk of pirates do not have the whit to do.

I would certainly not, nor encourage others to, circulate corrupted copies of their files containing viruses. Also I would never stoop, not suggest that you, insert into the ZIP a corrupted blMilWom.obj & rsr or similar, in the knowledge that it would not be spotted amongst the mass of other Poser files.

But some would ;)
