humans are unpredictable, as long as crowdfunding relies in good will and possible benefits of the project, there will always be people who take advantage of this, take money for themselves. that is human nature
Yes there will always be predatory crowdfunding project creators. But do you really believe that the friends of the predators are willing to vouch for them and offer insurance to project backers.
this is peer to peer insurance in other words this is people who leverage their reputation to have their friends provide collateral for future refunds. If you are a predator you don't have any friends.
