the▓ quality of news people find on Facebook,"▓ said Claudia Gurfinkel, leader of alliances with media for Facebook in Latin Ame▓rica, in a statement.Facebook said that after the launching of a similar initiative in the U.S., the organic distribution of fake news ▓fell by 80 per

cent.Furthermore, countries like Italy and the Philippines

have already seen similar alliances ▓with partners.Last month, amid a scandal due to private user information bein▓g disseminated to help design political ca
