PARIS—Twitter must disclose details on what it does to tackle hate speech online in France, the Paris appeals court ruled on Thursday, handing a win to advocacy groups that say the social network does not do enough. The decision provides ammunition to campaigners elsewhere in Europe who want tougher controls to prevent the spread of racist and discriminatory content on Twitter and other social media platforms. …The ruling sets France apart from countries such as Denmark, Britain and the United States, as the country’s stringent anti-racism laws allowed such litigation to succeed. In France, racism and anti-Semitism aren’t considered as opinions that can be held publicly, but as infractions.
