Twitter out to crack down on abusive tweets - Business Insider

Twitter has tripled the size of the team responsible for protecting users of the service, resulting in a five-fold increase in the speed of response to complaints, according to the general counsel. "We are also overhauling our safety policies to give our teams a better framework from which to protect vulnerable users," Gadde said. Changes included expanding the definition of banned "abuse" to include indirect threats of violence.
