YouTube may place age restrictions on content, for instance if the content includes violence or disturbing images, nudity, vulgar language or the portrayal of harmful activities.
This age restriction flag is placed by YouTube's review team. The flag prevents that users who are not logged in may watch the video, that logged in users who are not 18 years of age or older may watch it, and that users who are in Restricted Mode may watch it.
Users who are not signed in (in a Google or YouTube account), get the following message when they try to watch a video with an age restriction flag.

While you may be able to resolve the first message by signing in provided that you are 18 years of age or older, you may not watch these videos on YouTube if you are younger.
A common issue for users who are old enough is that they have not set a birthday yet. If a birthday is not linked to the Google or YouTube account, YouTube will display the age-restricted content message.

YouTube uses signals, automatic ones such as video titles or descriptions, and manual ones, to add the restricted mode flag to videos. Restricted mode furthermore blocks comments on YouTube.
