Flickr is an image and video hosting site and social network. Users can create a profile and contribute content, original or otherwise. Flickr prohibits content that is illegal, but sexually explicit material is permitted.

Since Flickr is owned by Yahoo, both Flickr and Yahoo’s Terms of Use apply. Flickr does permit nudity and adult content, but users are required to flag content as “Safe,” “Moderate” or “Restricted.” Flickr users can set their own pictures to private, and can also block search engines and 3rd party APIs from indexing or accessing their content. We recommend that young users mark their accounts as private.
