ELI5:How does Kickstarter prevent fraud?

Ive seen now quite a few kickstarters that have been very close to being funded, but missed out by only a small amount. What is there to stop the project organiser from contributing to his own kickstarter? By creating a dummy kickstarter account, using a different account, they could contribute a small amount to push it over the limit and guarantee they get thousands.. They wouldnt lose anything, as they donate to themselves. 

Obviously kickstarter must prevent this.. But how?

But if you need 16 grand for your project, and you get 15 and put in the last grand yourself, thats effectively the same as having just set the bar at 15.

I mean the bar is totally arbitrary, its just the point where you defined "yeah thats enough money to do this" if you decide 15 grand is enough and you can stump the rest yourself, who cares?
