Since the Paris terrorist attack on November 13, a famous group of hackers, Anonymous, promised to take down ISIS, the Jihadist group, who claimed responsibility for the attack. The online activists continue their fight against the extremists by using Rick Astley's "Never Gonna Give You Up."

According to Daily Mail, the "hacktivists" are trying to destroy the militant group's online members by linking them to a music video of 80s pop star, Rick Astley. They are disrupting the Islamic State's "social media activism" by invading its news feed by redirecting their followers to the classic hit song.

In fact, connecting people to the 1987 track has been an old-age internet prank, which, in the process, actually revives the 49-year-old singer's career. Anoymous posted a link of the video to a post under the display of "useful or interesting" info about the militants, which might make those who open it both baffled and frustrated.

Anonymous, who declared their all-out war in an anti-ISIS campaign following the tragic Paris attack that killed 130 people, decided to use the so-called "Rickroll" as their newest tool. They said they are going to post "Rickroll" links under the #SupportISIS hashtag that the Jihadists would use to make it easy for the aspirants who want to join the terrorist group.

 Moreover, Daily Express reported that the the online crusaders also set up the hashtag #OpISIS to help alert famous social media pages, especially Twitter, with the accounts used by the terrorists. These accounts are one of the ways they promote their terror acts and to recruit new members.

To reiterate, Anonymous launched their official announcement to fight the ISIS, warning that they would launch "its biggest operation ever against IS." A guy who was wearing their signature Guy Fawkes mask said, while speaking in French, "You should know that we will find you and we will not let you go."

They continued: "Hello, citizens of the world. We are Anonymous. It is time to realise that social media is a solid platform for ISIS's communication," the group's spokesman continued. "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 announcer continued. 

Additionally, Anonymous claimed that they already took down 20,000 ISIS-related Twitter accounts. They also declared their opposition against the terror regime after the Charlie Hebdo terror attack in January, which left 12 people dead.
