This is the kind of research work that should've been done before people donated, not now when the money's gone. It's all publicly available information, that only now that people fear their money has gone to waste is anyone even bothering to look up his history of scammy projects is really unfortunate.
I'm torn. I find it hard to sympathise with people who give away their money haphazardly like that, but given how stupid people are in general, I'd really like Kickstarter to make it safer for backers and make the creators shoulder more of a responsibility to deliver. It's too good of an idea to die because shit like this can happen.
