On Thursday, Twitter confirmed that over 1.2 million accounts had used the app to promote terrorism over a two year period.

In a statement on expanding and building transparency, Twitter’s Public Policy branch wrote that “Between August 1, 2015 and December 31, 2017, we suspended 1,210,357 accounts from Twitter for violations related to the promotion of terrorism.”

Twitter noted that 274,460 accounts were identified (and subsequently suspended) in the last reporting period, adding that “93% were flagged by internal, proprietary tools, and 74% of those accounts were suspended before their first Tweet.”

The announcement follows a particularly rough year for Twitter, which has struggled with the moderation of both users and content alike.
