A cohort of Twitter users with fake names and profile pictures have become a trusted source of information regarding drug cartel violence in Mexico

These citizen journalists choose to remain anonymous to avoid violent backlash from gang members, but their reports have become increasingly influential.

On Jan. 8, a team from Microsoft Research published a paper called “The New War Correspondents: The Rise of Civic Media Curation in Urban Warfare,” which details a social media study conducted over the past two years. Their main finding was that as Mexicans increasingly turn to Twitter for reports of violence, a core of mostly anonymous yet trusted curators have led the dissemination of public safety information.
