In May, Legal Advocacy joined allies to file an amicus brief in the U.S. Ninth Circuit Court of Appeals in the case of McGucken v. Valnet. The brief emphasized the importance of existing legal standards regarding who is responsible for material that is visible on one site but hosted by a different site (known as embedding). Embedding is a key tool for web users, including fans, and the OTW supports fans' ability to embed images on the AO3 and other sites.
