Despite a very vocal Twitter movement to #DeleteFacebook, new findings from investment bank and financial services company Goldman Sachs have revealed that the Cambridge Analytica data scandal, which saw the private information of up to 87 million Facebook users harvested and used to influence the 2016 US Election, had very little impact on the social network's traffic.

As reported by Business Insider, usage actually increased during its most difficult and scrutinized period, with the firm citing comScore numbers that point to a 7% year-on-year rise in mobile traffic from unique users in the US this past April, bringing the total to 188.6 million American users.
