Platform Policies and Community Guidelines

Twitter

Brand Safety @Twitter
Improving the health of the public conversation is a top priority for Twitter. Violence, harassment and other similar types of behavior discourage people from expressing themselves and create an unsafe environment, and this behavior has no place on Twitter. In addition to our work to combat this negative activity platform-wide, Twitter has invested in a suite of solutions aimed at ensuring a safe advertising experience for everyone who uses Twitter.
Amplify Publisher Program
The Amplify Publisher Program was created to make it easy for publishers to monetize video content on Twitter, and also turn-key for advertisers to align with brand-safe content.
The Twitter Transparency Center
While Twitter has been publishing biannual transparency reports since 2012, in 2020 these reports evolved into a more comprehensive Transparency Center covering a broader array of Twitter's transparency efforts. Twitter now includes sections covering information requests, removal requests, copyright notices, trademark notices, email security, Twitter Rules enforcement, platform manipulation, and state-backed information operations.
The Twitter Rules
Twitter's purpose is to serve the public conversation. Violence, harassment and other similar types of behavior discourage people from expressing themselves, and ultimately diminish the value of global public conversation. The Twitter Rules ensure all people can participate in the public conversation freely and safely.
