An anonymous reader writes: The Tehran cybercrimes court said the country has arrested eight people working for online modeling agencies deemed to be "un-Islamic." The women models were arrested for starring in photos on Instagram and elsewhere without wearing their headscarves, which has been required in public since 1979. A total of 170 people have been identified by investigators for being involved in online modeling, including 59 photographers and make-up artists, 58 models and 51 fashion salon managers and designers. The court's prosecutor Javad Babaei announced the the threats on TV, claiming modeling agencies accounted for about 20 percent of posts on Instagram from Iran and that they had been "making and spreading immoral and un-Islamic culture and promiscuity." He added, "We carried out this plan in 2013 with Facebook, and now Instagram is the focus."
