The twin developments come as Facebook is under intense scrutiny over privacy following the Cambridge Analytica scandal earlier this year. Allegations that the political consultancy used personal information harvested from 87 million Facebook accounts have dented Facebook’s reputation.

Since the scandal broke, Facebook has investigated thousands of apps and suspended more than 400 of them over data-sharing concerns.

The social media company said late Wednesday that it took action against the myPersonality quiz app, saying that its creators refused an inspection. But even as Facebook did that, it found its own Onavo Protect security app at odds with Apple’s tighter rules for applications.
