"In Q1[first quarter] we took action on 1.9 million pieces of ISIS and al-Qaeda content, about twice as much from the previous quarter," the release said. "Taking action means that we removed the vast majority of this content, and added a warning to a small portion that was shared for informational or counter speech purposes."
"In Q1 2018, 99 percent of the ISIS and al-Qaeda content we took action on was not user reported," the release said. "We found this material due to advances in our technology, but this also includes detection by our internal reviewers."
The median time for newly uploaded terrorist content to be flagged was less than one minute, the release 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, according to the release.
