The Abuse & Safety tool is here for you to resolve issues like harassment and bullying. This new feature will empower you to more easily and effectively handle these types of situations, without needing help from staff. Of course, we always encourage everyone to think things through before posting comments anywhere on the site. But if you don't get it right the first time, now you can simply delete your comment. To remove a comment that you've made, go to the "Text Comments" section below the video and click the "Remove" button next to your comment.
Helping you check yourself,
