"A young Jewish American man has been charged with pretending to be an Australian-based Islamic State jihadist after a FBI joint investigation with the Australian Federal Police based on information provided by Fairfax Media. Joshua Ryne Goldberg, a 20-year old living at his parents' house in US state of Florida, is accused of posing online as "Australi Witness," an IS supporter who publicly called for a series of attacks against individuals and events in western countries." "The fake jihadi also claimed a friendship with anti-Islamophobia campaigner Mariam Veiszadeh, but only to smear her reputation."
