Twitter last week announced it had suspended 235,000 accounts since February for promoting terrorism, bringing to 360,000 the total number of suspensions since mid-2015. Daily suspensions have increased more than 80 percent since last year, spiking immediately after terrorist attacks. Twitter's response time for suspending reported accounts, the length of time offending accounts are active on its platform, and the number of followers they draw all have decreased dramatically, the company said.
