Ime Archibong, Facebook's vice president of product partnerships said that the apps were suspended pending a rigorous investigation into whether services on Cambridge Analytica had improperly used or gathered users' any personal data.
A report by the New Scientist reveals yet another leak that affects data of over 3 million users that was "left exposed online for anyone to access" for over four years! The data was only supposed to be accessible through an approved research platform, but has since been discovered on a website with little to no protection.
Undeterred, Facebook answered a different question, saying that as of 2014, it had reviewed all apps seeking access to anything beyond basic data fields and rejected about half of those - some 299,000 apps in total.
The social network will be conducting a "thorough investigation" to check whether these apps have misused user data or not.
Over 280 people from almost 150 institutions eventually gained access to the full data set by registering as a collaborator to the project.
Developed by Cambridge University academics, myPersonality was revealed to have shared its collected data with 280 third-party researchers from prolific companies such as Facebook itself, Google, Microsoft and Yahoo.
But these 280 people or collaborators weren't alone in having access to data of almost 3 million users.

The people behind the data sets were David Stillwell and Michal Kosinski at the University of Cambridge's The Psychometrics Centre. However, their request was turned down by the myPersonality app team in 2013 because of the company's political ambitions. The man behind the Cambridge Analytica scandal, Alexandr Kogan, was named a collaborator on the myPersonality project until 2014, though "myPersonality" never actually shared any information with Cambridge Analytica.
Facebook has now suspended the myPersonality app (and around 200 other similar apps) in its efforts to investigate apps that may have violated its data privacy policies.
For one, what criteria did Facebook use to decide if an app should be suspended?
As a direct response to the Cambridge Analytica data scandal, Facebook recently launched a bounty program that rewards people who find and report any data misuse by app developers on its platforms.
Zuckerberg has testified in front of Congress about the misuse of data, and lawmakers have called on Twitter CEO Jack Dorsey and 's India-born CEO Sundar Pichai to testify as well. Facebook has so far suspended 200 apps that could be involved in data harvesting in this manner.
