After the Charlie Hebdo massacre in Paris this past January, the hacktivist group Anonymous set its sights on the Islamic jihadist perpetrators. #OpCharlieHebdo was aimed at tracking and taking down the social media accounts of all terrorists and their sympathizers including ISIS. They are apparently doubling down after the latest multiple terrorist attacks in Paris with #OpParis.
One day after the carnage, they took down over over 5,000 Twitter accounts, though I'm sure by now it's more. They've also set up websites in case you want to help. Here's the official Twitter account for #OpParis, where they are warning that ISIS is setting up fake accounts. So beware.
They have also published the names, addresses and phone numbers of 5 ISIS recruiters living in Afghanistan, Somalia and Tunisia, and one allegedly living in Europe.
Of course, there is no way to determine how many they have really shut down, and naturally they will sprout back up like nasty weeds, but at least ISIS is somewhat thwarted by the hackers.
Here is their latest video.
