The founder of Facebook - the second biggest US social networking site after MySpace - has admitted he “really messed up” when he launched his News Feed and Mini-Feed services.

Both services allow users to view the online activities of other members. The Guardian reported that hundreds of thousands of people found these services to be “spooky and stalker-esque”.

Founded in 2004, Facebook is aims to connect university, college and high-school students.

And Zuckerberg has told users to “Calm down. Breathe” whilst the services were “evolving”.

The services News-Feed and Mini Feed had been introduced to each user’s homepage, logging each and every action performed on the website such as posting a photo or updating their profile.

However, Zuckerberg admitted that the company had failed as the company did not build the proper privacy controls.

Last month Microsoft signed a three-year deal with Facebook to provide online advertising ’services.
