Fake news accounts on Facebook have been manipulating election campaigns around the world.
This was denounced by a former employee of the social network in a 6,600-word memorandum that he sent to his former co-workers. Data scientist Sophie Zhang said she made unsupervised decisions "that affected presidents."
"My hands are stained with blood," he wrote in the communication, part of which was published by the US media Buzzfeed.

Deception of the public In the communication, part of which was published by Buzzfeed without their permission, Zhang spoke of abuse and deception of the population.
"In the three years that I was on Facebook, I encountered multiple blatant attempts by foreign governments to abuse our platform on a large scale to mislead their own citizens and create international news on multiple occasions," Zhang wrote.
"I personally made unsupervised decisions that affected presidents and took action to enforce the law against so many prominent politicians globally that I lost count," he added.
Buzzfeed said he had shared only those parts of his statement that were in the public interest and reported that Zhang turned down a $ 64,000 severance package offered to him on the condition that he not share his memo internally.

"We have built specialized teams, we are working with leading experts, to prevent bad actors from abusing our systems, resulting in the elimination of more than 100 networks for coordinated inauthentic behavior," the company said.
"It is a very complicated job that these teams do full time. Working against coordinated inauthentic behavior is our priority, but we are also tackling the problems of spam and false participation," he added.
"We investigate every issue carefully, including those raised by Zhang, before taking action or going out and publicly making claims as a company," Facebook said.
Examples of jobs that the former employee refers to

• In India, Zhang worked to eliminate a politically sophisticated network of more than 1,000 users working to influence local elections in Delhi.

This explosive memo confirms long-held concerns about Facebook's ability to address foreign interference and disinformation campaigns.
But while most eyes have been on Russian meddling in American politics after the 2016 election, the testimony of this former employee draws attention to democratic events beyond the West.
Facebook's failure to address disinformation in other languages has come under scrutiny during the pandemic and this new information alleges that it has had trouble tackling interference campaigns in non-English speaking countries before.
The statement also raises great concerns about the enormous responsibility given to Facebook's junior moderators, whose decisions could affect democratic events, political outcomes and the lives of people around the world.
This will undoubtedly raise concerns about Facebook's work to address interference and misinformation campaigns as the next US election approaches. But it should remind us that Facebook plays a role in democratic events outside the United States.
