The new policy says Twitter will suspend or shutter any user account that engages in “hateful conduct” or whose “primary purpose is inciting harm towards others.” The company previously said users could not promote or threaten violence and in April added a ban on “promotion of terrorism.”

Under “hateful conduct,” the new policy warns users: “You may not promote violence against or directly attack or threaten other people on the basis of race, ethnicity, national origin, sexual orientation, gender, gender identity, religious affiliation, age, disability, or disease.”

The new policy also explicitly bans “creating multiple accounts with overlapping uses” aimed at evading suspension of a single account. Critics say Twitter has previously made it too easy for extremists to create new accounts as soon as older ones are shut down.
