Anonymous took down quite many twitter and fb accounts of people who were recruiting and brainwashing young people to go to syria. They further stated that
"The above video explains the attack was coordinated by “Muslims, Christians, Jews” alike. They are “hackers, crackers, Hacktivist, phishers, agents, spies, or just the guy next door… students, administrators, workers, clerks, unemployed, rich, poor.” They are also “young, or old, gay or straight… from all races, countries, religions, and ethnicity. United as one, divided by zero.”"
Massive Respect for them
