Kelly: We use very sophisticated social designs in terms of limiting access to people's information based on networks that they share in their real-world lives, and further, we use technology to look for anomalous behavior, things that may be concerning. It helps to keep our users safer and also to prevent spam and to create a more comfortable environment for our users. We have a pretty large customer service team that deals with both reports and with the potentially anomalous behavior highlighted by the technology.

IDGNS: Have you improved your response times when members report complaints about content or actions on the site? That seemed to be a big complaint Attorney General Cuomo's office had with Facebook at some point.

Kelly: Yes, absolutely.

IDGNS: Does Facebook do enough to make sure its average member understands how to manage the very granular privacy settings you offer?

Kelly: I think the average Facebook user understands very well that we take privacy extraordinarily seriously. There's always a balance to be struck between the ease of use and completeness in providing privacy control. We try to strike that balance very well, but we always listen to user feedback about that in terms of how we give them more control over what information they share and with whom.

IDGNS: How much monitoring do you do of, say, photos or videos uploaded to the site? Do those go through automated screening, or do you depend more on members manually flagging stuff they see?

Kelly: Most of the automated tools we've tested in terms of recognizing inappropriate images and things like that are ineffective. We've found that users are some of the best reporters on that, and our reporting infrastructure is extraordinarily effective in removing inappropriate content quickly and in holding those users who attempt to post them responsible by cutting off their account.

IDGNS: As chief privacy officer, what are some of your goals for this year?

Kelly: As the site and the Internet as a whole evolve, we want to continue giving people a great deal of control over what personal information they share and with whom. We want to continue to reflect the social graph very accurately, and privacy is a critical part of that, so we'll continue to bake it into the design of the site and provide people with the most effective privacy controls on the Internet.
