Facebook announced today it suspended around 200 apps on suspicion of mishandling user data, as part of its post-Cambridge-Analytica investigations.
Ime Archibong, Facebook VP of Product Partnerships, said the company's employees had, so far, audited thousands of apps that had access to large amounts of user data prior to 2014, when the company changed its developer policies and significantly reduced the quantity of data apps had access to.
Facebook to individually investigate each of the 200 apps

Archibong says Facebook plans to launch thorough investigations into each of the ~200 apps to determine if they misused user data.
"We will conduct interviews, make requests for information (RFI) — which ask a series of detailed questions about the app and the data it has access to — and perform audits that may include on-site inspections," Archibong said, describing what these thorough investigations mean.
He said all apps found misusing user data —similar to Cambridge Analytica— will be listed on this Facebook Help page. Facebook also plans to ban the infringing apps from accessing their platform for good.
It is unclear how long this app review process will last. Facebook says the entire process consists of two phases. The first phase, currently underway, consists of Facebook employees and external experts reviewing apps to identify those which had access to an extremely large amount of user data. The second phase consists of investigating each of the "suspicious" apps one by one, as described above.
Zuckerberg is keeping his promise

The entire app review process is taking place after Facebook CEO Mark Zuckerberg assured users that Facebook would clean up its act in a Facebook post on March 21.
The Facebook CEO promised three things. His employees have already taken care of #2 and #3 on this list, and now only the investigation (#1) remains.
First, we will investigate all apps that had access to large amounts of information before we changed our platform to dramatically reduce data access in 2014, and we will conduct a full audit of any app with suspicious activity. We will ban any developer from our platform that does not agree to a thorough audit. And if we find developers that misused personally identifiable information, we will ban them and tell everyone affected by those apps. That includes people whose data Kogan misused here as well.Second, we will restrict developers' data access even further to prevent other kinds of abuse. For example, we will remove developers' access to your data if you haven't used their app in 3 months. We will reduce the data you give an app when you sign in -- to only your name, profile photo, and email address. We'll require developers to not only get approval but also sign a contract in order to ask anyone for access to their posts or other private data. And we'll have more changes to share in the next few days.
Third, we want to make sure you understand which apps you've allowed to access your data. In the next month, we will show everyone a tool at the top of your News Feed with the apps you've used and an easy way to revoke those apps' permissions to your data. We already have a tool to do this in your privacy settings, and now we will put this tool at the top of your News Feed to make sure everyone sees it.
