A poll of 1 588 Facebook users conducted by Sophos has revealed the extent of member concerns over the popular social network's privacy settings.  The online survey shows that almost two-thirds of Facebook users are considering leaving, with 16% of those polled claiming to have already stopped using Facebook as a result of inadequate control over their data.

The poll asked Facebook users: Do you think you will quit Facebook over privacy concerns?:
* Possibly – 484, 30%
* Highly likely – 469, 30%
* Already have – 254, 16%
* No – 191, 12%
* Don't think likely – 190, 12%.
“Facebook has faced growing criticism over changes to the way that the social network can share user data across its site and with other websites.  Concerns have centred on the complexity and 'opt-out' approach to sharing member information with wider networks,” says Brett Myroff, CEO of regional Sophos distributor, Sophos South Africa.  
Media reports suggest that Facebook is planning to announce changes to its privacy settings within the next few days, but it is unclear as to whether any changes will be substantial enough to address user concerns.
"The poll indicates that a majority of users are fed up with the lack of control that Facebook gives them over their data. Many still don't know how to set their Facebook privacy options safely, finding the whole system confusing.  What's needed is a fundamental shift towards asking users to 'opt-in' to sharing information, rather than to 'opt-out'", says Myroff.
In response to the criticisms of Facebook's privacy policy, a number of campaigns, including a 'Quit Facebook Day', have been designed to further public awareness of the issues.
"A mass exodus from Facebook seems unlikely, but Facebook members are clearly becoming more interested in knowing precisely who can view their data," Myroff says.  
"People use Facebook to share private information and are unlikely to want their holiday snaps or new mobile number accidentally popping up all over the internet.  With this survey showing that only 24 percent of users are not thinking about quitting, Facebook will need to make sure further changes to the privacy policy are clear, concise and in the interest of making it easier for members to know exactly who has access to whatever they chose to upload."
