The company CEO Mark Zuckerberg had promised a thorough investigation and audit into apps that had access to information before Facebook changed its platform policies in 2014 - significantly reducing the data apps could access. Facebook first identifies apps that had access to "large amounts of data", like Cambridge Analytica, the data firm and Trump campaign consultant that harvested the information of 87 million unwitting users.
Archibong said that large teams of internal and external experts are working hard to investigate these apps as quickly as possible.
The investigation is one of a series of responses from Facebook following the data scandal, with new tools having also been rolled out to users to provide clearer access app permissions and privacy settings.

The company says it has now investigated thousands of apps and the result, so far, has been the suspension of 200 apps that are now pending an investigation. The company will apparently update that same site if its audits reveal any other apps have accessed your information.
"It will show people if they or their friends installed an app that misused data before 2015 - just as we did for Cambridge Analytica", Archibong continued. But at least you'll know.
