Europe to legislate social networking?

The EU's Internet security agency is calling for legislation "to police social-networking sites such as Facebook and MySpace," InfoWorld reports. The director of the European Network and Information Security Agency said that social sites are "useful social tools," but suggested that EU law needs to cover photo-sharing online because "currently there is no need to get a person's consent in order to post a photo of them." He also said more public education is needed about how social networking works, pointing to the problem that "many people don't realize that it's almost impossible to erase material once it has appeared on the internet."
