Just another case of a scam artist risking other peoples money on a hare brained idea that will never see the light of day !! Why doesn't indiegogo force people to have a fully working prototype before they publish these campaigns full of marketing wank ??
Because Indiegogo stand to make money, whether it is a fake or not. They have people in Indiegogo who work with project creators to promote and market the campaigns, put them in touch with glossy video producers, viral marketers, email spammers, etc. They might also have staff back projects and post warm messages, arrange special promotion like "staff picks", tie ups with vendors like Arrow. These people are like sales people, they get a bonus from campaign funding raised. Indiegogo are in the loop, they are part of the scheme. Check out the negative reviews on Glassdoor.
Basically, they do everything they can to help get a campaign funded, because they have a commercial incentive. Vetting a campaign to see if it is fake or stupid is absolutely the last thing on their minds. Of course, if they do reject campaigns, then they have less campaigns to make money from so are likely to market the remaining one more aggressively.
