I read this article, though from back in 2013. Essentially the takeaway is, unless you're a corporation you *could* have legal exposure if your project fails. I assume that is predicated on the plaintiff's ability that the failure involved something like fraud or negligence, or lack of "good faith effort" so to speak.
Has much changed since this article in 2013. The example basically describes that there was a good faith effort made but it failed basically due to incompetence, maybe some greed, etc. But it was not a scheme to try to defraud people for their money however the person still went bankrupt due to the lawsuits.

I know the Kickstarter terms of service basically is intended to absolve them of any legal liability. But if the project fails and very little or no money can be returned in a reasonable amount of time (not sure what's reasonable), and you're not incorporated, are you potentially screwed (as the funded, not the funder)
