Actually ISIS is using a sophiscated social media and propaganda campaign to recruit. IMHO if anonymous could leave the trail intact while hijacking their media and overlaying images of the truth on top of the propaganda they’d be doing a service.
What could say more with the cherub cheeked Austrian girl smiling with her ISIS warriors calling others to ‘the cause’ than picture of the yazidi mass graves of all women between 40 and up and picture s of the rest of the women at the sex slave auctions?
