“A lawsuit reported on by the Wall Street Journal alleges that Facebook was aware of issues on how the site measured views of video ads for more than a year before it disclosed the issue in 2016. A group of advertisers brought a lawsuit against the social media firm in 2016 for failing to disclose the error earlier, accusing Facebook of engaging in unfair business practices by publishing inaccurate metrics that overestimated how long users spent watching ads and ultimately misled advertisers.” https://www.breitbart.com/tech/2018/10/17/lawsuit-alleges-facebook-inflated-video-view-statistics-to-fool-advertisers/
