Indeed, there are no shortage of swindles out there, according to the most recent review of my Spam folder. There is already an appreciable amount of awareness out there of what are probably scams. Besides, there are already de-facto, and generally arbitrary, limitations imposed presently by popular crowd-funding services, e.g. Kickstarter. Kickstarter in particular seems to turn down applications it considers too entrepreneurial, and they do so inconsistently.
Perhaps this bill, albeit adjusted with some sensible yet minimal regulatory scheme, would permit crowd-funding schemes otherwise impossible. It could at least help encourage consistency in how crowd-funding could be (or not be) regulated.
