Facebook “Like Button” Links Every Page You Visit to Your Person Information
This is the new Facebook Like button that instantly spread across the Web upon its launch:
If you surf the Web while logged into Facebook, the button will display how many of your friends like the webpage you are on. That means it sends your personal identity back to Facebook to get the information.
Every page with a Like button that you visit while being logged into Facebook is being linked to your personal identity, including who your friends are, your interests, your activities, your phone number, credit card, and even to your religion and political party.
Free websites have to make money somehow, and your personal data is highly valuable.
From Voxy.co.nz:
For example, a Facebook user while on IMDb.com indicates that he likes a certain movie by clicking on the Facebook “Like” or “Recommend” button embedded in the site will create a data record. This data will be available to advertisers using Facebook and visible to anyone on the social network — even if the Facebook user has a “Friends Only” privacy setting on their account….Facebook terms Likes as a form of “social links” — claiming that they are better than a link because they can be related to a specific user.
One way to reduce the amount you are tracked by Facebook as you surf the Web is to always stay logged out of Facebook while browsing websites. One way to do this is to use one browser for browsing (e.g., Firefox) and a separate browser only for sites like Facebook and Google (e.g., Opera). That will give you somewhat more privacy on the Web.
