NEW YORK — In an about-face following a torrent of online protests, Facebook is backing off a change in its user policies while it figures how best to resolve questions like who controls the information shared on the social networking site.

The site, which boasts 175 million users from around the world, had quietly updated its terms of use — its governing document — a couple of weeks ago. The changes sparked an uproar after popular consumer rights advocacy blog Consumerist.com pointed them out Sunday, in a post titled "Facebook's New Terms Of Service: 'We Can Do Anything We Want With Your Content. Forever."'

Facebook has since sought to reassure its users — tens of thousands of whom had joined protest groups on the site — that this is not the case. And on Wednesday morning, users who logged on to Facebook were greeted by a message saying that the site is reverting to its previous terms of use policies while it resolves the issues raised.
