The Federal Court of Justice in Germany has declared unlawful Facebook's 'Friend Finder' feature. 'Friend Finder' invites users to grant it permission to vacuum up the e-mail addresses of contacts in the address book, thus allowing the social network to send an invitation to non-Facebook users to join the service. According to Forbes, the German Court ruled that the feature is a deceptive marketing practice, violating national laws on data protection and unfair trade practices.
