Unblocking someone on Twitter is the process of reversing a previous action taken to prevent them from interacting with your account. When you unblock someone, they will be able to view your tweets, follow you, and send you direct messages again.
There are a few reasons why you might want to unblock someone on Twitter. Perhaps you had a falling out with them in the past, but you’ve since reconciled. Or maybe you accidentally blocked them and didn’t realize it until later. Whatever the reason, unblocking someone is a simple process that can be done in just a few steps.
