WASHINGTON (APP) – Twitter said Tuesday it was take new steps to stem “abusive behaviour and hateful conduct” on the global messaging platform.

The move comes with social networks under pressure from the US and other governments following attacks in Paris and California to do more to weed out those plotting violence.

“We believe that protection from abuse and harassment is a vital part of empowering people to freely express themselves on Twitter,” said Twitter’s director for online trust and safety, Megan Cristina.

“Today, as part of our continued efforts to combat abuse, we are updating the Twitter Rules to clarify what we consider to be abusive behaviour and hateful conduct. The updated language emphasises that Twitter will not tolerate behaviour intended to harass, intimidate, or use fear to silence another user’s voice.”

The new rules say Twitter users “may not make threats of violence or promote violence, including threatening or promoting terrorism” and “may not incite or engage in the targeted abuse or harassment of others.”
