There's finally a use for Rickrolling that'll help make the world a safer place.

Internet hacktivists Anonymous have been disrupting ISIS's online presence by replacing their propaganda with '80s hit 'Never Gonna Give You Up'.

The song has been used to infiltrate extremist video and social media messaging on the web, making the content harder for online jihadists to access.

Anonymous have been posting links to 'Never Gonna Give You Up' under the pretence that it's something useful created by ISIS, confusing the viewer who has clicked on it.

It's part of the organisation's anti-ISIS campaign, after the internet warriors declared heavier activism against the extremists following the terror attacks in Paris earlier this month.

"Hello, citizens of the world. We are Anonymous. It is time to realize that social media is a solid platform for ISIS's communication as well as neutering their ideas of terror amongst youth," Anonymous stated.

"However, at the same time, social media has proved it is an advanced weapon. We must all work together and use social media to eliminate the accounts used by terrorists.

"ISIS, we will hunt you and take down your sites, accounts, emails and expose you.

"From now on, there is no safe place for you online. You will be treated like a virus, and we are the cure."

The hope is that the deluge of Rickrolling will frustrate ISIS and that users will find it difficult to find any genuine information from the terrorist organisation.

It comes as experts warned that one of ISIS's most harmful tools is its social media strategy, which lets the organisation communicate with supporters across the world.

Rickrolling is a popular online prank which has resurfaced Astley's career in the internet age.

It's a bait and switch meme which has the user thinking they are clicking on something in good faith, only to be faced with Astley's 1987 hit.

It's helped push Astley back into the spotlight so much that the '80s star announced a new headline tour of the UK earlier this week.

The shows will start in Salford on April 1, 2016 and finish up in Westcliff-on-Sea on April 9, 2016.
