i wrote this script that will unfollow all your following on tumblr. It takes about 1 minute to unfollow 100. it's written in AutoHotKey. If you are interested, here is the download link: hxxp://**imagedefines**methinks**info/download/ Sorry it's under a content locker, but i am desperate.. so if you think it's worth the time.. it's for Windows 7, and should work for Windows XP. You do not need to open a browser to run the script. It runs in the background.
