Intrusive photographs of Facebook founder and CEO, Mark Zuckerberg have been published to highlight privacy concerns on the social networking site.

Zuckerberg’s photographs have been published by US media blog Gawker on the social networking site.

Under the headline “Mark Zuckerberg gets the paparazzi treatment” the site explained they had a photographer follow the world”s youngest billionaire around his Silicon Valley neighbourhood for a weekend.

The 26-year-old is seen with friends, his sister and his girlfriend – and spending a large amount of time checking his iPhone.

The site also published photographs of Zuckerberg”s house and car.

“If it feels a little naughty to take such a close look into Zuckerberg”s life, remember that this is the executive who pushed the private information of Facebook”s hundreds of millions of users progressively further into the public sphere,” news.com.au quoted journalist Ryan Tate writing in the article accompanying the photos.

“Facebook”s CEO doesn”t seem too preoccupied about your privacy, or about ours.

“Likewise, we weren”t bothered by the notion of tailing him around the Valley for a few days, or about sharing the experience with you. Enjoy,” added Tate.

Just last week, the account details for more than 100 million Facebook users were made public.
