Hide, delete, or disable comments on your posts.
Twitter may carry a more “anything goes” culture of commentary, but your Instagram is your domain — and it’s much easier to control who says what on your content. This is especially important if you manage a business account.
To Filter Comments by Keyword:
In the Instagram mobile app, navigate to “Options” and select “Comments.” From here, you can toggle on “Hide Inappropriate Comments” and even enter specific keywords you’d like the app to police within each comment.
To Delete Comments:
Tap the speech bubble icon below the comment you’d like to delete, and swipe lightly to the left over this text. Select the garbage can icon that appears to delete this post. You can also do this to your own comments.
To Disable Comments Entirely:
To clarify, you can’t turn off comments across your entire profile; you can only disable them for individual posts.
To do so, start posting an image on which you’d like nobody to comment. When you reach the page to add a caption, tags, and location, tap “Advanced Settings” at the very bottom. This will open a screen where you can easily switch on an option labeled “Turn Off Commenting.”
