Pornhub and two other adult sites are suing the European Union over a landmark digital content law, the Digital Services Act, which imposes age verification and other obligations on large platforms. The European Commission last year named Pornhub, Xvideos and Stripchat as a category of “very large online platform” under the act, which includes obligations such as age verification measures for minors and creating a library of adverts published on their sites. Companies that fall foul of the law can be fined up to six percent of their global turnover. This lawsuit follows similar legal challenges by online retailers Amazon and Zalando.
