Twitter is once again tightening its rules around what users are permitted to say on the platform. The company introduced an updated “violent speech” policy, which contains some notable additions compared with previous versions of the rules.

Interestingly, the new policy prohibits users from expressing “wishes of harm” and similar sentiments. “This includes (but is not limited to) hoping for others to die, suffer illnesses, tragic incidents, or experience other physically harmful consequences,” the rules state. That’s a reversal from Twitter’s previous policy, which explicitly said that “statements that express a wish or hope that someone experiences physical harm" were not against the company’s rules.
