I created this script because I couldn’t really find anything out there for it. Both the Twitter support page and all the Twitter APIs out there had the ability to unblock people, but only if you knew who you wanted to unblock. Recently I tried the Twitter Karma service that could Mass unfollow / block people (hence my last couple scripts). I clicked the wrong button one time and it blocked a whole bunch of people. But say your not a klutz like me, maybe you just forgot who you’ve blocked over time.

This script will dump the list of people you block and unblock them all. Now you could expand this to get the names of each individual that you block but that’s an API call for each. Let me know if there is a better way, right now, the only way to figure out who was unblocked is through the 302 response that is generated with each request that sends you to the users page that you unblocked. (Push this script through a proxy to see it.)
