The Israeli company Archimedes Group spent over $ 800,000 running Facebook ads and their accounts had nearly 3 million followers, Facebook said in a blog post announcing the moves Thursday.
Archimedes Group used false accounts and "represented itself as locals, including local news organizations, and published alleged leaked information on politicians," Facebook said.
The company focused mainly on Nigeria, Senegal, Togo, Angola, Niger and Tunisia but also had some activity targeting Latin America and Southeast Asia, according to Facebook.
A site that appears to belong to the Archimedes group prides itself on its "important roles in many political and public campaigns, including presidential elections and other social media projects worldwide."
"Archimedes has created and operated its own unique area in social media, "it continues.
CNN Business has reached out to the company for comment.
In the blog post, Nathaniel Gleicher, Facebook's head of cybersecurity policy, wrote "The site's administrators and account owners often published political news, including topics such as elections in different countries, the candidate's views and criticism of political opponents." [1
