In a blog post, Twitter has said that it has deleted more than 125,000 accounts since mid-2015 for promoting terrorist acts, and most of them were either affiliated with or supported Islamic State group, reported The Guardian. The social media company used human judgment as well as inputs form teams of specialists in the United States and Ireland to identify these accounts. "We condemn the use of Twitter to promote violent terrorism. This type of behaviour, or any violent threats, is not permitted on our service," the company said in a statement.

Twitter, however, said that there was no "magic algorithm" for identifying terrorist content on social media. “Global online platforms are forced to make challenging judgment calls based on very limited information and guidance,” a spokesperson said. Technology companies have long policed their content for signs of extremism. Social media firms met with US officials in Davos last month during the World Economic Forum to discuss ways of weeding out IS recruiters from social media. While Facebook suggested posting anti-IS content to quell the terrorist outfit, technology executives also discussed developing an algorithm that can immediately flag IS content.
