Yep...there are a lot of questionable kickstarter projects...even ones that have done incredibly well despite having no real product to show. The bigger problem, in my view, is how your actions affect the rest of the Kickstarter community. As soon as people start failing on delivering and running out of money (which has already happened), people will begin to lose faith in Kickstarter, and this hurts people who want to launch legitimate, rational, and honest fund-raising efforts.
