Two weeks ago, Facebook posted revised terms-of-service guidelines on its Web site. On Monday, it tried to squelch a tempest that has blown up around them.
The changes give Facebook the right to keep and use information a user has created and posted, even after the person has terminated his or her membership.
Without ths license, Facebook couldn't help people share information, says Mark Zuckerberg
One new section, reported on this weekend by the Consumerist blog, reads as follows:
“The following sections will survive any termination of your use of the Facebook Service: Prohibited Conduct, User Content, Your Privacy Practices, Gift Credits, Ownership; Proprietary Rights, Licenses, Submissions, User Disputes; Complaints, Indemnity, General Disclaimers, Limitation on Liability, Termination and Changes to the Facebook Service, Arbitration, Governing Law; Venue and Jurisdiction and Other.”
Previously, users of the social networking site had the right to remove their content at any time.
On Monday, founder Mark Zuckerberg said in a blog post the company won’t share personal information against a user’s wish.
At the same time, there is no system today that lets someone share an e-mail address, for example, and then control what the person receiving the address does with it.
Zuckerberg writes: “When a person shares information on Facebook, they first need to grant Facebook a license to use that information so that we can show it to the other people they’ve asked us to share it with. Without this license, we couldn’t help people share that information.
“When a person shares something like a message with a friend, two copies of that information are created—one in the person’s sent messages box and the other in their friend’s inbox. Even if the person deactivates their account, their friend still has a copy of that message. We think this is the right way for Facebook to work.”

The box is designed to help site developers introduce social Web features to their online properties, He said.
The add-on makes use of Facebook Connect, a sign-on service that lets Facebook members log into other sites with their Facebook IDs and comment using the real names and Facebook profile photo.
Since Connect was launched in December, more than 6,000 developers have used it, with some of their sites experiencing a 40 percent to 50 percent increase in the number of posted comments, Facebook said.
