Twitter does not permit hateful conduct, abuse, threats of violence, or targeted harassment on our service. These type of behaviors do not encourage free expression or foster open dialogue; they stifle them. As part of our overall health initiative, we are investing resources in personnel, policies, product, and operations to ensure we are promoting conversation and debate that is civic-minded, open, and healthy. We have brought on independent academics from Oxford and Leiden universities to hold our entire approach to account. However, this is not just a Twitter issue, it is a societal one... As our CEO Jack Dorsey stated in front of Congress in the U.S., serving the public conversation means disincentivizing abusive behaviors, removing automated attempts to deceive and promote disinformation at scale, and ensuring that when the public comes to our service, they gain a constructive, informed view of the world's conversation. We all have a part to play in this - we are committed to playing ours.
