Note: this article is for users you have personally blocked. If they are blocked to you because you subscribed to a moderation list, see [How to Unblock Someone Blocked by a Moderation List].
To unblock a user you have personally blocked, follow the following steps:
1: go to the profile page of the user that you blocked.
If you don't remember who you blocked, there is a way to see a list of the users you blocked on Bluesky.
2: on the blocked user's profile page, click on the "Unblock" button that appears where the "Follow" button normally would appear. A dialog box will appear asking if you want to unblock them or not.
3: click on "Unblock" in the dialog box. The user will be unblocked and you'll be able to see their posts again.
