Who blocked me on Twitter?

Currently, there's only one definitive way to find out whether you have been blocked or not as there's no easy-to-find list. Here's how you can see who blocked you on Twitter:

1. Navigate to the account that you suspect has blocked you;
2. If you're actually blocked, instead of their tweets you'll see a message saying "You're blocked. You can't follow or see @username's Tweets.";
3. If you're still able to view their tweets normally, it means you are not blocked.
