Kickstarter does not seem to approve every project. As discovered here [1], there are currently at least 70,000 unpublished projects. For comparison, between 2010 and 2011 they launched 38,000 projects. [2]
Kickstarter projects had a 46% success rate in 2011. But this figure only includes projects they approved to be listed on the site. I have always wondered what percentage they reject. With 70,000 private projects what can we conclude about the real success rate?
