Facebook
is suing a South Korean firm it accuses of unlawfully using information to sell marketing and advertising.
The social network is asking a judge to force Rankwave to allow it to audit the firm’s
activities to see if
user information was
obtained and potentially sold.
A source at
Facebook told the BBC it was as yet unable to say how much information or how many users may be affected.
The network said the move would “send a message to developers that
Facebook is serious regarding enforcing our policies”.
“Facebook was investigating Rankwave’s information practices in regard to its advertising and marketing services,” said Jessica Romero, Facebook’s director of platform enforcement.
“Rankwave failed to co-operate with our efforts to verify their
compliance with our policies, which we require of all developers using our platform.”
The BBC was unable to reach Rankwave for comment on Friday.
