Twitter sold users’ data to Analytica researcher

LONDON/NEW DELHI: Social media company Twitter Inc sold data to the University of Cambridge academic Aleksandr Kogan who harvested millions of Facebook users’ information without their knowledge, it has emerged, although the company has clarified that no private data was accessed.

It isn’t clear whether any of the data pertained to Indian users.

Twitter does not share a break-up of users by region, the platform has less than 100 million users in India.

Kogan, who created tools that allowed political consultancy Cambridge Analytica to psychologically profile and target voters, bought the data from the microblogging website in 2015, well before the recent scandal, involving use of the data of Facebook users, came to light.

According to The Daily Telegraph, Kogan bought data on tweets, user names, photos, profiles and locations over a fivemonth period between December 2014 and April 2015 through his company Global Science Research (GSR).

Twitter said it had banned GSR and Cambridge Analytica from buying data or running advertisements on the website and that no private data had been accessed, while Kogan insisted the data had only been used to create "brand reports" and "survey extender tools" and that he had not violated Twitter's policies.

The daily reported that Twitter charges companies and organisations for large data sets that are particularly useful for gleaning public opinion or receptiveness to certain topics and ideas, although Twitter bans companies from using the data to derive sensitive political information or matching it with personal information obtained elsewhere.

A Twitter spokesman confirmed the ban and said: "Twitter has also made the policy decision to off-board advertising from all accounts owned and operated by Cambridge Analytica.

This decision is based on our determination that Cambridge Analytica operates using a business model that inherently conflicts with acceptable Twitter Ads business practices.

"Cambridge Analytica may remain an organic user on our platform, in accordance with the Twitter Rules."
