Anonymous hacktivists announce plan to 'mock' IS

Hacking group Anonymous has vowed to take out social media accounts supporting the Islamic State militant group during a planned day of rage.

According to the online Daily Mail, the group was planning to post photographs of dead IS terrorists while bombarding their twitter feeds with pictures of goats.

The anarchist collective said it wants to devote December 11 to an anti-IS day of rage.

The IS thrives off fear and hopes that by its actions it can silence all of us and get us to just lay low and hide in fear, the collective said.

"We will show them that we are not afraid, we will not just hide in our fear, we are the majority and with our strength in numbers we can make a real difference. We will mock them for the idiots they are...."

One group of activists has decided to post memes of terrorists with goats suggesting that many of them have an unnatural physical interest in the cloven-footed animals.

This follows an earlier attempt by activists to ridicule IS by posting photographs of terrorists online with rubber ducks.
