Twitter Rules: We will remove any accounts maintained by individual perpetrators of terrorist, violent extremist, or mass violent attacks, and may also remove Tweets disseminating manifestos or other content produced by perpetrators.
We want Twitter to be a place where people can find reliable information and express themselves freely and safely without feeling burdened by unhealthy content. In the aftermath of terrorist, violent extremist and mass violent attacks, we know many want to express compassion for victims, condemn the attacks and/or the perpetrators, and discuss how these incidents impact people and their communities. Some might also wish to share manifestos or other similar content produced by the attack’s apparent perpetrator or an accomplice, either to express outrage or condemnation of the perpetrator’s possible motives.
The violence that these perpetrators engage in, and the rationale they outline in manifestos or other means that normalizes hatred and discrimination, may further jeopardize the physical safety and well-being of those who are targeted, and has the potential to inspire future attacks. Exposure to these materials may also cause harm to those that view them.
We believe the hateful and discriminatory views promoted in content produced by perpetrators are harmful for society and their dissemination should be limited in order to prevent perpetrators from publicizing their message. As a result we may remove Tweets that include manifestos or other similar material produced by perpetrators, even if the intention behind the Tweet is not abusive. However, if there is a clear and explicit intent to provide additional context and counterspeech, we may consider keeping the Tweet up.
What is a manifesto?
We define a manifesto as a statement by a perpetrator outlining their motivation, views, or intent to engage in a violent attack. A manifesto can be in the form of a written document, social media post, audio recording, video, external link, or letter or other forms of content. It may be shared in the aftermath, or at any period before a violent attack. A manifesto can be linked to the event through a statement of warning or intent.
Who are the individual perpetrators of terrorist, violent extremist, and mass violent attacks?
Violent attacks claimed by a violent organization or by a member of such organizations are covered under our violent organizations policy. We do not require that a person have been confirmed as members of terrorist organizations or other violent groups, nor that they have any official affiliation with any group, organization, or ideology, for us to enforce on content under this aspect of our policies.
