I already don't like this site. The privacy policy is contradictory: "We will not share, sell, rent, or trade your Personally Identifiable Information with other parties. We may share your information with Authorized Third Party Service Providers. We provide services and products through third parties. These “Third Party Service Providers” perform functions on our behalf, like sending out and distributing our administrative and promotional emails." Which third party service? I was on the site for 3 minutes, and got no less than 3 pop-up prompts requesting that I enter my email address for some kind of newsletter (not going to happen). This site has all of the features of a spam harvesting queue.
