Mass Twitter Action
Mass Twitter Retrieve
This script allows you to mass follow, defollow or retrieve friends or followers from Twitter. It doesn't check if your Twitter username and password are correct, so it's up to you to enter the correct values. Make sure you enter your username and not your email address.
The script isn't perfect for usability: It could use some beautiful AJAX requests so the user will know the request is being processed. Feel free to edit the source code, but make sure you follow the Creative Commons 3.0 rules. Use or implement this script at your own risk.
