LinkedIn Accused of Hacking Customers’ E-Mails for Contacts

LinkedIn Corp., owner of the world’s most popular professional-networking website, was sued by customers who claim the company appropriated their identities for marketing purposes by hacking into their external e-mail accounts and downloading contacts’ addresses.

The customers, who aim to lead a group suit against LinkedIn, asked a federal judge in San Jose, California, to bar the company from repeating the alleged violations and to force it to return any revenue stemming from its use of their identities to promote the site to non-members, according to a court filing.
