Facebook, the world's largest social media company, filed a lawsuit against CJ ENM subsidiary Rankwave with a U.S. court, saying that Rankwave has abused Facebook data for marketing and advertising.
Rankwave is an analytics company that provides social network services (SNS) data solutions. It analyzes SNS data to figure out the interests and tendencies of users and recommends accurate target products and provide marketing services to advertisers.
Facebook made an announcement on May 10 (local time) saying that "Facebook has analyzed data practices of Rankwave in terms of advertising and marketing services and Rankwave did not cooperate in our investigation on compliance with Facebook's policies."
According to the accusation, Facebook estimates that Korean company Rankwave uses the Facebook platform to operate more than 30 applications. Facebook claims that Rankwave's misconduct has harmed Facebook's reputation, trust and goodwill.
Meanwhile, Rankwave, headquartered in Samseong-dong, Seoul, was acquired by CJ E&M in 2017 and became a CJ subsidiary.
