Just days after GreatGameIndia exposed how American and Japanese companies could be hacking Indian elections, a recent Bloomberg report has revealed how a secret unit of Facebook has helped create troll armies for governments around the world including India for digital propaganda to influence elections. Under fire for Facebook Inc.'s role as a platform for political propaganda, co-founder Mark Zuckerberg has punched back, saying his mission is above partisanship.

But Facebook, it turns out, is no bystander in global politics. What he hasn't said is that his company actively works with political parties and leaders including those who use the platform to stifle opposition—sometimes with the aid of "troll armies" that spread misinformation and extremist ideologies.

The initiative is run by a little-known Facebook global government and politics team led from Washington by Katie Harbath, a former Republican digital strategist who worked on former New York Mayor Rudy Giuliani's 2008 presidential campaign as well as 2014 Indian elections.
