Bilibili
China's largest video platform, hosting hundreds of millions of videos. For an archives researcher it matters as a possible home for reuploads and Chinese-language material that exists nowhere else. There is no keyless English-facing API, and search from outside China is gated by geo-checks and captchas, so this is a follow-the-link resource: open the site and search there.
