Twitter has doubled its efforts to purge extremist content from its site since April, bringing the total number of accounts suspended to 360,000 since the middle of 2015, the company announced Thursday in a blog post. That should greatly reduce the Islamic State’s ability to reach out to potential followers and distribute its propaganda, according to experts.

The move follows Twitter’s previous announcement they were suspending 125,000 accounts “for threatening or promoting terrorist acts primarily related to ISIS.” “Today we are announcing that we have suspended an additional 235,000 accounts for violating our policies related to promotion of terrorism in the six months since our February 2016 post,” the company reported. The company also said that daily suspensions were up 80 percent as screeners move more quickly to stop extremist posts.

Twitter stepped up efforts to push ISIS off its networks after the widow of Lloyd “Carl” Fields Jr., a U.S. contractor killed by ISIS, filed a suit against them in January, claiming that Twitter was partially responsible for the death because the company provided a means for ISIS to recruit and raise funds for terrorism in violation of the Anti-Terrorism Act. Twitter argued that the platform was neutral and that they bore no direct responsibility. They won the suit earlier this month.

Other social media companies such as Facebook and YouTube are employing automation and machine learning to spot and tag extremist content (pictures and video) before it spreads, thanks to a program led by the Counter Extremism Project, a nonprofit group that bills itself as a clearinghouse of research on extremist groups. Twitter has been the holdout. In March, they said that there is no “magic algorithm” for identifying extremist content.
