These crowdfunding platforms heavily rely on trust between backers and creators. I wonder how many failed projects, scams, etc. it will take before that trust is eroded? If fraud isn't policed better, Kickstarter will permanently lose many of its best backers. Example: I once invested in a small Indiegogo art project. The creator was supposed to produce and ship a small book of comic strips to the backers. This was a very doable project but the creator never delivered and has to this day never refunded the backers. I haven't funded anything since and probably never will.
