SAN FRANCISCO — For the second time in as many weeks, the U.S. Court of Appeals for the Ninth Circuit has weighed in on a controversial federal anti-hacking statute.

Ruling Tuesday, the court found that a defunct social-media aggregator, Power.com, violated the Computer Fraud and Abuse Act by accessing Facebook servers and scraping data from users’ Facebook profiles after receiving a cease-and-desist letter from the social-media giant.
