You have platforms that thrive on this : Kickstarter, Indiegogo.

They are filled with concepts, prototypes, what ever that's sold as end products.

Yet they ask for money, here it's offered the possibility to get more information.

Yes, there are many people who lie. That’s what makes it a problem, just like with other types of pollution.

But in my experience your characterization of crowdfunding is mostly wrong. While projects tend to describe their product as they intend for it to be in final ready form, the whole concept of crowdfunding makes it clear enough that backers help fund something that isn’t yet a reality, and that there is risk involved.
