"Government information requests" include both emergency and routine legal demands for account information issued by law enforcement and other government agencies.
"Routine requests" (aka non-emergency requests) are legal demands issued by government or law enforcement authorities (e.g., subpoenas, court orders, search warrants) that compel Twitter to turn over account information.
Twitter may disclose account information to law enforcement in response to a valid "emergency request" if we are provided with sufficient information to support a good faith belief that there is an imminent threat involving danger of death or serious physical injury to a person, and we have information relevant to averting or mitigating the threat.
“Accounts specified” include Twitter and Periscope accounts identified in information requests we have received. This number may include duplicate accounts or requests for accounts that do not exist or were misidentified. This number does not include multiple identifiers associated with one account within one request (e.g., if a request contains an email address and the associated @username, we count them as one account identified).
"Compliance rate" refers to the percentage of information requests where Twitter produced at least some of the requested account information.
“Preservation requests” refers to government and law enforcement requests made in accordance with relevant law that require Twitter to maintain the specified account data pending the issuance of valid legal process to obtain that data.
"Legal demands" include a combination of court orders, where a judge has ruled that content violates the law, and other legal demands from government and law enforcement agencies, or other third-party requesters to remove content based on their legal authority, such as content that is in violation of an injunction.
"Accounts specified" includes the number of accounts identified in the requests we’ve received.
"Compliance rate" refers to the percentage of requests where Twitter took a specific action to remove content (e.g., Tweet or account withheld, Tweet removed, or an account was suspended) in response to a legal demand.
"Accounts withheld" refers to accounts that have been withheld in their entirety.
"Tweets withheld" refers to Tweets that have been withheld at the individual Tweet level, and does not count the total number of individual Tweets from the "Accounts withheld" column.
"Accounts TOS" refers to the number of accounts where either the account was suspended or some content was removed for violating Twitter’s TOS (which includes both Twitter’s Terms of Service and the Twitter Rules).
