Twitter out to crack down on abusive tweets

Twitter said Thursday that it is cracking down on mean, hateful or menacing tweets that cross the red line from free speech into abuse.

Twitter is overhauling its safety policy and beefing up the team responsible for enforcing it, along with investing "heavily" in ways to detect and limit the reach of abusive content, general counsel Vijaya Gadde said in a column published by the Washington Post.
