Facebook announced that it will block Google’s Friend Connect service from accessing data on its social network site because Friend Connect does not comply with their privacy policy.

Facebook said Google’s service is allowing third party sites to have access to the user information that is transmitted while exporting profile information.

The decision comes as a blow to the joint effort of the three companies, Facebook, Google and MySpace, to increase data portability over the internet.

Facebook has said that Google will be allowed access again as soon as it will solve the issues, but Google said it doesn’t understand what exactly it is expected to do.
