YouTube is giving aspiring suicide bombers and run-of-the-mill jihadists a big thumbs down.

The video sharing giant has launched an experimental service that scours the site for ISIS propaganda and other extremist posts.

Then, YouTube redirects the junior jihadis to ads that torpedo ISIS’s ludicrous claims.

“The Redirect Method uses Adwords targeting tools and curated YouTube videos uploaded by people all around the world to confront online radicalization,” YouTube parent Google said in a news release.

“It focuses on the slice of ISIS’ audience that is most susceptible to its messaging, and redirects them towards curated YouTube videos debunking ISIS recruiting themes.”

Google has also launched a broader strategy targeting terrorist-flavoured content across their multiple platforms.

The Redirect Project was developed by the search titan to develop software based on YouTube’s advertising tools. An eight-week trial saw more than 320,000 viewers watch more than 500,000 minutes of footage.

The company said certain keywords, identified by Adwords, trigger the redirection to the anti-terrorism videos.

“This open methodology was developed from interviews with ISIS defectors, respects users’ privacy and can be deployed to tackle other types of violent recruiting discourses online,” the company added.
