Twitter CEO Jack Dorsey said the company is actively focused on security and has closed about 125,000 accounts related to terrorism.
"We're being very aggressive in shutting these accounts down," Dorsey said on Wednesday at the Code Conference in Rancho Palos Verdes, California. "We get help from governments all over the world in pointing out these accounts."
Dorsey, the Twitter co-founder and Square CEO who came back to run the microblogging service last year, was joined on stage by activist and Black Lives Matter member Deray Mckesson.
They met during the Ferguson protests in 2014 that followed the fatal shooting of Michael Brown by a police officer. Ferguson is part of the greater St. Louis area, Dorsey's hometown.
