What can I upload? What will Twitter remove?
Our goal is to provide a service that allows you to discover and receive content from sources that interest you as well as to easily share your content with others. We also want you to understand our guidelines for making sure your content is labeled appropriately.
For the most part, using common sense won’t steer you wrong. If you upload media that might be considered sensitive content such as nudity, violence, or medical procedures, you should consider applying the account setting “Mark my media as containing sensitive content”.
We do not mediate content, whether that content is an image or text; however, some content is not permissible by law. All content should be marked appropriately as per our guidelines. You may not use our service for any unlawful purposes or in furtherance of illegal activities. International users agree to comply with all local laws regarding online conduct and acceptable content.
Uploaded images that are reported and that are determined to violate the law will be removed from the site and your account will be suspended. Please review the Twitter Rules for more information on these violations.
Images that have been marked as containing sensitive content will have a warning message that a viewer must click through before viewing the image. Only users who have opted in to see possibly sensitive content will see these images without the warning message. Check out this article for more information on settings and best practices.
What happens to reported media?
After you flag someone else’s media, the Twitter team will review and determine if that media requires a warning message in order to comply with Twitter’s Media Policies. Please remember that by flagging media you are bringing it to the attention of the Twitter team. The flagged content will not automatically receive a warning message or be removed from the site.
Please review this article if you’d like to learn more about what happens to your account if your media is flagged.
