Washington: Twitter began implementing a new policy aimed at curbing use of the social network to incite violence, and to crack down on abuse and harassment on the service.
The new rules are the latest implemented by social networks aiming to stem violence and harassment while attempting to safeguard freedom of online speech.
"We need to ensure that voices are not silenced because people are afraid to speak up," said Twitter's head of product management Shreyas Doshi in a blog post.
"To that end, we are today announcing our latest product and policy updates that will help us in continuing to develop a platform on which users can safely engage with the world at large."
Some of the changes were outlined last week in media by Twitter general counsel Vijaya Gadde.
On Tuesday, Doshi noted that Twitter had updated its policy on violent threats "so that the prohibition is not limited to 'direct, specific threats of violence against others' but now extends to 'threats of violence against others or promot(ing) violence against others."
He said the previous policy "was unduly narrow and limited our ability to act on certain kinds of threatening behavior."
Twitter's new policy also allows the social network to "lock" abusive accounts for specific periods of time, which could help crack down on so-called cyberbullying and spam.
"This option gives us leverage in a variety of contexts, particularly where multiple users begin harassing a particular person or group of people," Doshi said.
Doshi also noted that Twitter would be testing "a product feature to help us identify suspected abusive Tweets and limit their reach."
The new tool, which was not described in detail, could help Twitter identify abusive activity by looking at "a wide range of signals and context that frequently correlates with abuse including the age of the account itself, and the similarity of a tweet to other content that our safety team has in the past independently determined to be abusive," said Doshi.
