Members of loose-knit hacktivist collective Anonymous have declared "war" on ISIS, in what Anonymous claims is its "biggest operation ever."
But not everyone is thrilled about this.
There are growing concerns that, while well-intentioned, Anonymous' attempts to battle the militant Jihadist group are doing more harm than good.
"Anonymous from all over the world will hunt you down."
After the Paris terror attacks on Friday — that left more than 120 dead and hundreds injured — Anonymous publicly declared its intention to take the fight to ISIS, which has claimed responsibility for the attacks.
A YouTube video aimed at the group featuring a man in Anonymous' signature Guy Fawkes mask announced that Anonymous "from all over the world will hunt you down."
