How do you unblock a user you've previously blocked?
Most Helpful Girl
You can unblock users by going to your profile and clicking on the tab that says "Blocks" which is underneath "Follows" on the left side bar. From that page, just click the red "X" under the users name you want to unblock. You should see a pop-up asking if you want to unblock the user, click "yes." :)0
