SAN FRANCISCO — With urging from Facebook, Craigslist, eBay and others, the U.S. Court of Appeals for the Ninth Circuit has agreed to reconsider a controversial ruling about website operators’ duty to warn about potential harm by third parties.

A three-judge panel set new arguments next month in Doe v. Internet Brands, after ruling last fall that the operator of a website for aspiring models could be sued for failing to warn they were being targeted by rapists.
