Facebook now puts the figure at 96 134, well up from the 59 777 it earlier admitted to.

While only 13 South Africans are known to have downloaded Cambridge Analytica’s “thisisyourdigitallfe quiz on Facebook, the way Facebook exposes user’s data means that information about those users; friends was potentially compromised.
