• Hateful conduct: 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. We also do not allow accounts whose primary purpose is inciting harm towards others on the basis of these categories.

• violent threats;
• wishes for the physical harm, death, or disease of individuals or groups;
• references to mass murder, violent events, or specific means of violence in which/with which such groups have been the primary targets or victims;
• behavior that incites fear about a protected group;
• repeated and/or or non-consensual slurs, epithets, racist and sexist tropes, or other content that degrades someone.

• Context matters.
• Some Tweets may seem to be abusive when viewed in isolation, but may not be when viewed in the context of a larger conversation. While we accept reports of violations from anyone, sometimes we also need to hear directly from the target to ensure that we have proper context.
• The number of reports we receive does not impact whether or not something will be removed. However, it may help us prioritize the order in which it gets reviewed.
• We focus on behavior.
• We enforce policies when someone reports behavior that is abusive and targets an entire protected group and/or individuals who may be members.
• This targeting can happen in any manner (for example, @mentions, tagging a photo, and more).
• We have a range of enforcement options.
• The consequences for violating our rules vary depending on the severity of the violation and the person's previous record of violations. For example, we may ask someone to remove the offending Tweet before they can Tweet again. For other cases, we may suspend an account.

• Retweets look like normal Tweets with the author's name and username next to it, but are distinguished by the Retweet icon and the name of the user who Retweeted the Tweet.
