In an article in the Huffington post a while back, it said the Feds are now going after people who don't follow through. I also hope while they are at it, they can do something to help protect these vulnerable people giving money to support projects without proper education about what they are supporting.
The Feds go after people who just walk away with the money. They do not, and should not, go after people who fail to achieve the objective -- that would defeat the point of crowdfunding.
