Look we won't lie, some people just need to cool it on the posts.
Instagram has solved this so you don't have to clock or unfollow anyone just simply mute them so you don't see every post they make but can check out what they post when you're ready to.
Instagram is planning to roll the mute button out "over the coming weeks," and just like Twitter or Facebook or even Instagram's current "Stories" feature, people you mute won't know you did it, and you can mute or unmute them at any time.
Here's to never having the "why'd you unfollow me?" talk with a friend or ex ever again!
