I'm sure most of them perfectly know what they're doing. The purpose of most of those debunked Kickstarters was never to deliver a working product, it's to get a few hundred thousand to live on while pretending to try and deliver something. It seems to be legal as I never hear about legal repercussions for these people, so I guess why not?
