According to Cnet, users can easily avoid the catch. While installing a Facebook app, users are asked whether to allow access to the “basic information” and thecurrent address and mobile phone number,” and if users click on “Allow” the information will become public.
To avoid it, Cnet has some suggestions to remove contact information from your Facebook profile:
1. Log into Facebook and click Home in the upper right corner.
2. Click Edit My Profile.
3. Click on Contact Information at the bottom of the left column.
4. Make sure that the Mobile Phone, Other Phone, and Address fields are blank.
Though the facebook blog post tried to ensure that these permissions only provide access to a user's address and mobile phone number, not their friend's addresses or mobile phone numbers, many users who have already suffered from lack of security, find it hard to believe.
On the other hand, Sophos, an Internet security firm, warned in a blog post that the change could herald a new level of danger for Facebook users. Also Sophos has termed Facebook's new move a recipe for disaster.
