Most notably, the MPA (which comprises major entertainment companies Disney, Netflix, Paramount, Prime Video & Amazon MGM Studios, Sony, Universal, and Warner Bros. Discovery) has flagged the major anime streaming site HiAnime under “Priority Notorious Linking and Streaming Sites.“

Priority Notorious Linking and Streaming Sites refer to “the most significant global notorious linking and streaming sites“, with HiAnime just one of three sites in this category. The MPA’s comment on HiAnime reads:
“Vietnam. Hianime, formerly known as Zoro[.]to and Aniwatch[.]to, has a global ranking of 159 with 244.2 million visits from 17.54 million unique visitors in August 2025, according to SimilarWeb. The site provides access to a range of content, especially anime content. The hosting location is masked using Cloudflare’s reverse proxy, but the site is currently believed to be operated from Vietnam.“

Joining HiAnime, some other anime websites and “Piracy-as-a-Service” offerings that the MPA is aware of include the fellow Priority site, Cuevana, as well as AnimeFLV, Gogoanime (and its many spin-offs), Anime-Sama, Cineby, Hydrahd, Nunflix, Redecanais/Futemax, Rezka, AnimeUnity, Streamed[.]su, Videasy, Vidlink, and AnimeFly.

The MPA considers Piracy-as-a-Service offerings as encompassing “a suite of often off-the-shelf services that make it easy for would-be pirates without any technical knowledge to create, operate, and monetize a fully functioning pirate operation, such as website templates, databases of infringing content, and hosting providers specialized in servicing infringers.“

The report also flags what it considers other facilitators of piracy, such as certain hosting providers and domain registrars, DDoS protection services, and even Cloudflare.
