How can a website / service be operated in 2015 without any contact or legal information? How am I supposed to use this for my personal information without being able to read the privacy statements or knowing who's operating the service to what purpose? Edit: To make the reason for my comment clear, there was no link in the footer like there is now at the time I wrote it.
Not to mention some jurisdictions requiring a privacy policy, like California.
One of the best "features" of the internet is that it is jurisdictionally grey.
Otherwise, why not just subject the entire world to the stringent requirements of China?
