Since it became known that Cambridge Analytica misappropriated the personal information of millions of Facebook users a question remained open to the public: what other data had Dr , Aleksandr Kogan access to?
Twitter confirmed on Telegraph on Saturday that GSR, Koga's own commercial company, had acquired a one-time API access to a sample of public tweets over a five-month period between December 2014 and April 2015. Twitter said Bloomberg that after an internal review, the company has found no access to private data about Twitter users.
Twitter sells API access to large organizations or companies to measure opinions or opinions during various events or on specific topics or ideas.
Here's what a Twitter spokesman said to The Telegraph:
Twitter has also made the po of its decision to avoid advertising from any accounts that Cambridge Analytica owns and operates. This decision is based on our determination that Cambridge Analytica works with a business model that conflicts with Twitter Ads' acceptable business practices. According to the Twitter rules, Cambridge Analytica can still remain an organic user on our platform.
Of course, this does not have the same scope as the data that users have collected on Facebook. Twitter data about users is much less personal. The location on the platform is opt-in and generic, and users are not forced to use their real name on the platform.
Nonetheless, it is clear how broad the Cambridge Analytica data collection was prior to the 2016 elections.  We have reached Twitter and will update it when we hear it.
