The Supreme Court heard arguments on Tuesday in a case that could have major implications for the way websites rank content. The case involves a lawsuit brought by the family of Nohemi Gonzalez, who was killed in a 2015 ISIS attack, against Google for its automatic recommendations of user content. During the hearing, justices questioned how to protect websites from liability for content they do not create or control, while still exposing harmful content to liability. The court's decision could have a major impact on the way websites rank content.
