San Francisco, May 15: A data set of over 3 million Facebook users collected via a personality app was available to download freely for anyone for almost four years, New Scientist reported.

The data set was collected via the personality quiz app "myPersonality" by academics at the University of Cambridge.

"The data was highly sensitive, revealing personal details of Facebook users, such as the results of psychological tests.

"It was meant to be stored and shared anonymously, however such poor precautions were taken that deanonymising would not be hard," the report said.

The data sets were controlled by David Stillwell and Michal Kosinski at the University of Cambridge.

"More than 6 million people completed the tests on the myPersonality app and nearly half agreed to share data from their Facebook profiles with the project," said the report.

Alexandr Kogan, at the centre of the British political consultancy firm Cambridge Analytica scandal, was previously part of the project.

"Cambridge Analytica had approached the myPersonality app team in 2013 to get access to the data, but was turned down because of its political ambitions," the report said.

Facebook last month suspended "myPersonality" from its platform, saying the app may have violated its policies.

The social media giant on Monday said that is auditing each and every app that has access to the data of its users and has already suspended 200 apps which failed to comply with its policies.

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.

"To date, thousands of apps have been investigated and around 200 have been suspended -- pending a thorough investigation into whether they did in fact misuse any data," Facebook said.

If Facebook finds evidence that these or other apps did misuse data, it will ban them and notify users via Help Centre on its website.

Appearing before the US Congress in April, Zuckerberg told lawmakers that his own personal data was part of 87 million Facebook users that was improperly shared with Cambridge Analytica.

Lucknow (PTI): The Lucknow Bench of the Allahabad High Court on Friday ordered a probe by the special task force (STF) into alleged irregularities in the rejoining of a teacher at City Intermediate College in Barabanki, observing that the reinstatement appeared to be prima facie illegal.

The court also directed the recovery of the salary paid to the teacher during the disputed period.

A bench of Justice Rajeev Singh passed the order on a petition filed by the college management committee. The court expressed doubts over the roles of the District Inspector of Schools (DIOS), Barabanki, the college principal and the teacher concerned and hence, directed a detailed inquiry into the matter.

Taking note of alleged manipulation of records and misleading submissions, the court ordered the immediate transfer of the Barabanki DIOS to ensure a fair probe. It also directed the initiation of disciplinary proceedings against the then joint director of education of the Ayodhya division.

In its order, the court found that the teacher, Abhay Kumar, was initially appointed as an assistant teacher in 2018 but joined an Eklavya Model Residential School in Chhattisgarh as a lecturer in June 2024 without obtaining permission from the management. His subsequent request to retain the lien was rejected.

Despite this, he was allowed to rejoin the Barabanki College in September 2025 on the directions of the joint director of education and the DIOS, and was even paid the salary for October 2025. The court termed the rejoining "wholly illegal" and lacking any legal basis.

The bench also expressed concern over lapses in communication within the education department and directed the Uttar Pradesh chief secretary to ensure that official orders are communicated through email and WhatsApp as well, to prevent disputes.

The matter is next listed for hearing on May 28 when a compliance report is sought.
