Facebook's reputation has taken a massive hit in the past week, after the revelation that it allowed Cambridge Analytica, a political consultancy working for the Donald Trump campaign, to wrongfully harvest the profiles of 50 million Facebook users without their permission to identify and target potential voters during the 2016 U.S. election.

A new poll shows a significant erosion of trust in Facebook, with only 41 percent of Americans saying that they trust Facebook to obey laws that protect their personal information.

Users have been highlighting that the data has been collected after downloading information the company holds on them.
