If you're an avid Twitter user, you may have blocked a large amount of users -- everyone from spammers to the occasional harasser -- without even realising it. It's also possible to block someone accidentally; for example, prior to Twitter's layout change in 2010, the "message," "unfollow" and "block" links on a user's profile page were right next to one another, making an unintentional block easy. An application called Who I Block shows you a list of everyone you've blocked in the history of your Twitter usage.

Skill level:
Moderately Easy


  1. 1

    Visit the Who I Block? website at

  2. 2

    Click "Sign in with Twitter" and "Allow" to give the application access to your account history.

  3. 3

    View the list of Twitter users you've blocked. To unblock a user, follow the link to the user's Twitter profile and click "Undo" next to the "Blocked" or "Blocked and reported for spam" message above the user's tweets.
