Twitter has suspended nearly one million user accounts for promoting terrorist violence over the course of the last two years, the company reported on Tuesday.

In its bi-annual transparency report Twitter reported that its own internal control measures had eliminated 75% of the terrorist accounts before they had even posted a single tweet. The company said that only 1% of account suspensions were the result of government reports.

Major social media and tech companies have come under increasing scrutiny in recent years for the rampant terrorist activity which occurs over their platforms, particularly with recruitment efforts and the dissemination of propaganda.

According to its own report, Twitter has increased their response to government requests of terms of service violations, but the majority of requests went without Twitter taking action.
