I've stored copies/scans of all my crucial info (Passport, driver's license, ticket confirmation numbers, airline elite cards, etc) on my personal website for years. Kudos to someone for taking a very simple idea and making a buck, but I, as a savvy technologial person, would never pay someone else to store such sensitive information on their computers. You guys have mentioned hacks, but what about the company turning sour and dissemenating the info to people who will pay for it?
If it smells bad, it probably is...
