Unfollow All People You Follow (on Twitter)

unfollowallI’m not sure whether I will use this tool called Unfollow All or not, but right now, I don’t have plan to unfollow Twitter users I’m following. But, if I — or an account I maintain — need to do this, this tool should help me do the dirty job.
What is Unfollow All?

This tool will automatically unfollow everybody you’re following. There will be no further confirmation. Please be patient as this may take some time, depending on how many people you are following. After completion, unfollows may take some time to take affect.
