How to use this tool

This website simply displays a list of the users you have blocked on Twitter. To view your list of blocked users, just click the Sign in with Twitter button and allow access for this application. You can then click on the Show my blocked users button to display a detailed list of your blocked users. You have the option to Unblock each user if you feel you have made a mistake or are in a forgiving mood. Each unblocked user will be listed at the top of the page, where you have an option to Follow if you feel the need.

I never want to see my blocked users again, what's the point?

It's a fair question. Twitter's block feature is there to avoid contact with spam-merchants and cyber-bullies, so your list of blocked users is likely to be a rogues gallery, which you don't want to waste much time reviewing.

However, because the user interface on twitter.com is frequently redesigned and constantly tweaked, it is quite common to hear of Twitter users inadvertently blocking people. So if your friend asks you: have you blocked me?, this tool gives you a quick way of checking.

Blocking too many accounts? Try the alternative view

The Twitter API calls to show your blocking list are rate-limited to 15 calls per user in any 15 minute period. Each call returns 100 users, so 1500+ blocked accounts are too many to show from this page. An alternative view is under development, which shows a page of 100 users at a time. You can try this method at: http://test.blockedby.me

Is that all? Surely I've blocked a bigger number than that.

Many people expect the size of their Twitter blocked list to be larger than the number returned by blockedby.me. The explanation for this is that Twitter only returns valid accounts in your blocked list, so a good many accounts have probably succumbed to suspension and deletion since you blocked them.

Can I see a list of who has blocked me?

No, Twitter does not make that information available. However Twitter is now much more direct about individual users who have blocked you and simply states "This user has blocked you from following them" if you click on their Follow button on twitter.com. Previously Twitter used to mask this information behind a protected tweets smokescreen.

Statistical Summary: 79 users blocked on average

Based on data from the 108879 unique users, who have queried their blocked list with this tool, the average number of people blocked per account is 79. Note that the maximum blocked count has been used for each unique user in this statistical analysis, as users often use the tool more than once and the blocked value will therefore vary over time.

Are there any profile factors strongly correlated with the size of the blocked list? The Pearson correlation coefficents are shown below. The strongest correlation is with the no. of Tweets, which makes some sense. The more you tweet, the more people you will choose to block. Having said that, the correlation (R=0.0905) is not very strong.
