Just stating the facts - in fact here is the EXACT warning when you go to pledge to help a project on KS:
" Important
Kickstarter does not guarantee projects or investigate a creator's ability to complete their project. It is the responsibility of the project creator to complete their project as promised, and the claims of this project are theirs alone."
IndieGoGo has similar warnings, you can view their "Trust and Safety" page here:
http://www.indiegogo.com/trustIt's a "cover your arse" clause. It's pointing out the campaign organisers are the ones who are legally responsible for doing what they say they will - the service (be it KS, IndieGoGo, Pozible, etc) isn't legally liable.
Of course, every so often a campaign gets runs by somebody who has no business doing so, and this is what happens:

As I said before, the core bit is that you are putting your rep on the line. You know who I am, and with a bit of Google searching you would be able to find out where I live, so screwing people over is generally a pretty dumb thing to try ;)
