Official YouTube Blog: Why flagging matters

We have trained teams, fluent in multiple languages, who carefully evaluate your flags 24 hours a day, seven days a week, 365 days a year in time zones around the world. They remove content that violates our terms, age-restrict content that may not be appropriate for all audiences, and are careful to leave content up if it hasn’t crossed the line. As YouTube grows, we continue to scale our policy enforcement resources to meet your needs as a community. Flagged content, however, doesn’t automatically get removed. YouTube is an important global platform for information and news, and our teams evaluate videos before taking action in order to protect content that has an educational, documentary, scientific or artistic purpose.
