“They also represented them selves as locals, such as regional information organisations, and published allegedly leaked info about politicians,” Nathaniel Gleicher, head of cybersecurity coverage at Fb, wrote in the submit.
An investigation found that some of the exercise was connected to Israeli corporation Archimedes Group, Mr Gleicher explained.
“This organisation and all its subsidiaries are now banned from Facebook, and it has been issued a stop and desist letter,” he stated.
The people powering the phantom accounts used all over $812,000 (£634,941) for adverts between December 2012 and April 2019, Facebook explained, and these ended up compensated for in Brazilian reais, Israeli shekel and US bucks.
