• The user who posted the content will receive notification that he or she has violated the Twitter rules.
• This user will not see the name or any information about the person who filed the report against him or her.
• Reported Tweets and notifications will disappear from your timeline and notifications tab once you refresh the page.
• Reporting a violating Tweet or account may not always result in an account being permanently suspended. In some instances, an account may first be temporarily locked. The offending content will be hidden from view and the user must delete it if he or she wishes to remain on Twitter’s platform.
• Visit this page to learn more about reporting a Direct Message or conversation. Please note that once you report a DM or conversation, it will be deleted from your Messages inbox.

What’s the difference between reporting a user and reporting a Tweet?
If an entire account is dedicated to posting unauthorized images of you or if your unauthorized image is an account’s background picture or avatar, then you should report the entire user account. If there is one specific tweet that contains your unauthorized image and/or other abusive content, then you should report at the individual Tweet level.
