Redaction: the removal of information from a legal document owing to confidentially or other reasons. For example, news organizations redact names of people mentioned in their articles. Twitter uses this term when it removes content that it believes may violate any agreement you have with it. For example, if you follow someone who follows another person who follows us, then we can remove the third-party's content from their feed. In this case, we'd use the redactor tool to delete that person's account. When you share content through Twitter, you are giving permission for anyone to re-share that content. If you want to be sure no one breaks out your photo, stop sharing it until you've taken it down. Otherwise, you might get notified when it gets shared elsewhere online. The Twitter rules also say they can suspend your account if necessary, which means all your tweets will be deleted and everyone who followed you will be removed from their updates. You won't even know about it until you try to log in the next time. In conclusion, redacting means removing content that is confidential or otherwise prohibited from being shared.
