It's coming out this morning that all of this was the work of one 20-year-old from Florida named Joshua Ryne Goldberg. He was the fake white supremacist on /pol/. He stole Josh Bornstein's identity. He was the fake ISIS account Australi Witness. The dude was Jewish and rusing everybody.
[Rita] Katz said, in an interview with the Age, that the Twitter user is “part of the hard core of a group of individuals who constantly look for targets for other people to attack,” and recruits for ISIL.
The guy made death threats so he is in trouble.
