Last week, media reported that the personal information of about 50 million Facebook users had been harvested without their permission by the Cambridge Analytica firm, which had links to US President Donald Trump's presidential campaign headquarters, in order to develop a mechanism that would predict and influence the behavior of voters.
According to media reports, Facebook learned of the fact that Cambridge Analytica had access to the personal information of the social network's users in 2015, after which it demanded that the data analysis firm delete the acquired information. The firm assured Facebook that its requirement had been fulfilled, however, last week Facebook learned that the data had not been completely destroyed.
