Tampermonkey UserScript to auto-click Follow/Unfollow Buttons on Crowdfire

README.txt

Press CTRL+SHIFT+Y (PC) or COMMAND+SHIFT+Y (Mac) to auto-click all the follow or unfollow buttons on Crowdfire,
with a small delay (200ms) in-between.

Sends a notification when the process completes. Saves a lot of time, and makes it much easier to grow your following
without all the clicking.

Just an FYI, this doesn't work anymore due to changes Crowdfire had to make to comply with Twitter's rules.
