YouTube has removed nearly 50,000 videos of preacher Islamist radical Anwar al-Awlaki, who was killed in a drone strike in 2011.

Awlaki was recognized by the preaching of violence as a religious duty, although at the time of his death, his family denies that he was a terrorist.

The rest of the videos are mostly documentaries and news, reports the New York Times.

The BBC understands that this is a result of the review human, not machine learning.Slow to act

To help ensure that the videos stay off of YouTube, once the human flag a video for removal it is run through a formatting system that creates a digital fingerprint or “hash”.

Uploaded videos are compared with this hash to detect when people are trying to share copies of prohibited content.

Awlaki published many different types of videos on YouTube.

Some were explicit calls to violence, but others were comments about Islam and its history.

Most of these videos are believed to have been purged from the site.

If he were alive today, Awlaki would have been prohibited from owning a YouTube channel, because he was named as a terrorist in the united kingdom and the united states government lists.

Against the extremism of the groups presented its first complaints about Awlaki videos in 2009, but until last year it was still possible to find copies of his most explicitly violent material on YouTube.

A long series of complaints and reports of the working groups, to counter extremism, detailed Awlaki’s influence and called on YouTube to act.

Alexander Meleagrou-Hitchens, of the George Washington University program of research on extremism, told the New York Times that “YouTube” deserved recognition” for the removal of the videos.

YouTube design often led people to discover Awlaki’s content without realizing it, he said.

However, he added, Awlaki videos still were easy to find on other video sites, and social networks.
