Over its lifespan, Twitter has avoided directly monitoring and filtering content, preferring instead to let users flag offensive tweets for it to screen at its leisure. The result has been policing that's irregular at best, which critics claim fostered a safe haven for bullies and racists: to wit, it took years for the service to finally block one of its most reported pitchfork-rallying trolls last month. This hesitance to step in is haunting the company as evidence surfaced that it refused to take down key content posted by ISIS proponent and cleric Anjem Choudary after he was arrested in 2014. Only after news broke about it earlier this week did his account disappear.
Thus Twitter's increasing vigilance of suspected terrorist activity: Daily suspensions for violating its prohibition on supporting extremism are up 80 percent from last year. In addition, it's expanded its teams reviewing reported violations, is moving faster to suspend accounts and improving its ability to sniff out banned users returning with new usernames. How effectively these actions will curb terrorist support and communication on the platform has yet to be seen.
