Unblocking people on Steam is the process of removing them from your blocked list, allowing them to contact you and view your profile again. To unblock someone, open your Steam Friends list, click the “More” drop-down menu, and select “Manage Blocked Users.” Find the user you wish to unblock and click the “Unblock” button.
There are several reasons why you might want to unblock someone on Steam. Perhaps you had a falling out with a friend and have since reconciled, or maybe you accidentally blocked someone and want to give them another chance. Whatever the reason, unblocking someone is a simple process that can be completed in a few seconds.
