ISIS' New Target: Mark Zuckerberg They're also none too happy with Twitter's Jack Dorsey By Michael Harthorne, Newser Staff Posted Feb 24, 2016 6:05 PM CST 18 comments Comments "If you guys were the destroyers of Facebook, you'd have destroyed Facebook." (AP Photo/Manu Fernandez) (Newser) – Angry over efforts to keep their propaganda off social media, ISIS targeted Mark Zuckerberg of Facebook and Jack Dorsey of Twitter in a 25-minute video released Wednesday, Vocativ reports. Vocativ found the video on Telegram, one of the less popular social-media sites ISIS has been forced to use thanks to a crackdown on terrorist activity by Facebook and Twitter. The video shows a picture of Zuckerberg and Dorsey with bullet holes through it and threatens to basically end both Twitter and Facebook. "If you close one account we will take 10 in return and soon your names will be erased after we delete your sites, Allah willing, and will know what we say is true," Vocativ quotes the video. Social media is instrumental to ISIS in recruiting and training followers, USA Today reports. But just this month Twitter boasted of suspending 125,000 accounts for terrorism-related reasons. "We feel a pretty strong responsibility to help make sure that society is safe," USA Today quotes Zuckerberg at a conference this week. The video claims ISIS has hacked more than 10,000 Facebook accounts, 150 Facebook groups, and 5,000 Twitter accounts, changing profiles and posting ISIS propaganda, as payback. Experts say Twitter and Facebook's efforts against ISIS are working, though they warn it could be easy for that work to be undone by the terrorist group.
