(Reuters) -Capital One must face a lawsuit by social media creators who said the bank's free browser extension stole their sales commissions when consumers bought their products and services. In a Monday night decision, U.S. District Judge Anthony Trenga in Alexandria, Virginia said creators plausibly alleged that Capital One knew or should have known that it diverted their commissions by overriding tracking codes that showed consumers had seen their content. The proposed class action involves affiliate marketing, where creators promote content through links that appear on their platforms and social media channels, and are provided by online merchants and third-party marketers.
