Facebook’s recent changes have attracted a lot of controversy. U. S. Senators and online privacy advocates are urging Facebook to roll back recently launched features. Concerns are being raised that these new features can compromise the privacy of around 400 million Facebook’ users worldwide.

A group of U. S. senators raised serious objections on Tuesday over Facebook’s alleged moves to share user’s personal information with other websites without their agreement.

New York Senator, Charles E. Schumer pointed that social networking sites should be more responsible with user’s information and it should not be allowed to be used by a third party. He addressed a letter along with three other senators to Facebook founder, Mark Zuckerberg.

This is being also followed closely by online privacy advocacy groups. One of these groups is already planning to lodge a complaint with Federal Trade Commission. It argues that there should be transparent guidelines related to the use of user’s information by various social networking sites.

Regulators in Europe and Canada are also following these recent developments. Web experts also feel that social networking websites need to understand and address privacy related issues better.

These reports were denied by Facebook representatives. They feel that Facebook users retain complete control over their personal information and the freedom to share it with anyone they agree to.

Many studies have already proved that American people feel that websites ask for far too much information, than necessary.
