Facebook had a wild west approach to user data, says ex-employee

Facebook had "wild west" approach to looking after its users' data and had "little detection" of any violations of its policies, a former employee of the company has told British MPs.

Speaking amid allegations election consultants Cambridge Analytica (CA) harvested the data of millions of Facebook users for the purposes of political targeting, whistleblower Sandy Parakilas claimed the company "had very few ways of discovering abuse or enforcing on abuse when it was discovered".
