The family of Nohemi Gonzalez, a 23-year-old U.S. citizen killed during a 2015 series of Islamic State terror attacks in Paris, sued YouTube parent company Google, arguing the video sharing site not only provided a platform for videos containing terrorist content, but also recommended the videos to users. 

The family alleges that YouTube algorithms allowed "hundreds of radicalizing videos inciting violence and recruiting potential supporters" to be targeted to users of the platform. 

Section 203(c)(1) of the Communications Decency Act says companies like YouTube, Google and Twitter are generally shielded from liability for information uploaded by their users, but the case, Gonzalez v. Google, asks whether it should apply when tech companies make "targeted recommendations."
