Now, it’s fast and easy to “unfollow” someone on Twitter.
Here’s official documentation from Twitter’s FAQ page:
Stop following someone by visiting the profile page and using the drop down box, or send the reverse commands via text, web, or API: leave username, or off username.
Coming soon: Dynamic and scalable enterprise class functionality for unfollowing anyone.
Important: Please DO NOT follow unfollowme on Twitter, because we’re not here to be followed. We are here to be unfollowed and to help you to be unfollowed. Follow?
