These videos do not need to get into the public access – on the idea, they can only be viewed on a limited link.
Users of “Yandex” found that with the help of the search engine, you can find videos from YouTube, which have limited access mode. This mode means that the videos should not be available in the search engines, and users can see them only by reference.
Earlier, “Yandex” was accused of indexing private documents from the Google Docs service. Then, users assumed that the link-based access function in any similar application should be used only with the minimum value of data on this link.
