Does anyone know whether, if you were to create a fake project and get it funded then just walk away with the cash, there would be any legal action from KickStarter themselves, and/or the potential for legal action from one or more of the backers?

I figure that, because of the "it's not a guarantee that the person(s) you back will succeed", it ought to be possible to successfully come across as a legitimate person who did his best, spent all the funds on the project and ended up not managing to actually finish it.
