Social network giant, Facebook found and removed 1.9 million social-media posts by the Islamic State and al Qaeda terrorists during the first three months of 2018, using new anti-terror algorithms.

Detection technology has been critical to progress detecting terrorist posts, with the Facebook counterterrorism team growing from 150 last June to 200 at present, with plans to continue expanding the team, the release explained.   

The median time for newly uploaded terrorist content to be flagged was less than one minute, Facebook noted. However, because content receives less attention the longer it remains on line, the Facebook team also went back and reviewed older posts, accounting for 600,000 removals in the January-March quarter.
