- Launch Instagram from your iPhone Home screen.
- Go to the photo or video that has the comment you want to moderate.
- Tap the Comment button just like you would to leave a new comment.
- Scroll to the comment you want to moderate.
- Swipe from right to left to reveal the Trash can button.
- Tap the Trash can button.
- Choose if you simply want to delete the comment or if you want to report it for abuse.
That's it, the offending comment will be gone and those coming across your Instagram photos or videos will no longer be subjected to anything that's decidedly less than social.
