Copyright and takedown requests

Contributors must confirm that they own, or have permission to share, everything they upload, and choose a licence for it.

If you believe a material infringes your copyright, open the material and choose Report a copyright problem. You do not need an account. Describe the original work and include a good-faith statement; we will review the complaint and may remove the material while it is investigated.

Contributors are told when a complaint about their material is upheld and may submit a counter-notice, which an administrator considers before any material is restored.

Other problems (inaccurate, inappropriate or spam content) can be reported by any signed-in user from the material's page.
