Kylie Jenner knows quite a bit about Instagram . . . she has accounts for her dogs [1], is queen of the risqué selfie [2], and posts more often than many professional photographers. But according to a recent interview [3] with Teen Vogue, the youngest of the Kardashian clan is oblivious to one very important tech hack: how to get rid of Instagram comments. Instead, she simply deletes and reposts pictures. "Today I posted my Instagram picture three different times," she told the magazine. "I kept deleting it and re-posting it because I kept looking at the comments and they were bad comments. And I was like, 'Ahhh!' and I kept re-posting it."

We don't blame her — it's not easy to figure out, but there is a supersimple way to delete replies on Instagram. Whether you want to get rid of followers' mean remarks or even misspelled one of your own replies, we've got your guide to purging the comments section on your profile.

• On your own photos — If there are undesirables (or spammers) commenting on your photos, delete the unwanted post by hitting the comment button underneath a picture and swiping the comment to the right. It will reveal a trash can to delete and a shortcut to reply!
• On others' photos — You can only delete your own comments from other people's Instagram snaps. Hit the comment button and swipe to the right to delete. If there's a comment that really disturbs you, swipe to the left and hit the exclamation point to report spam or obscenity.
