// ==UserScript==
// @name Twitter Remove Non-Followers
// @namespace http://userscripts.org/users/28
// @description Remove Twitter friends who don’t follow you back. Click the "Remove marked users" button at the bottom of the list to activate.
// @include http*://*twitter.com/following*

ABOUT
=====

This script highlights the "remove" buttons for "friends" who don’t follow you
back on your Twitter Friends pages. A new action button is added at the bottom
of the page. When you click this button, all marked friends will be removed.

The scrip marks only users who:
<ul>
<li>don’t follow you ("don’t return the love")</li>
<li>have their updates unprotected (you can always remove these manually if you want).</li>
</ul>
By default, no action is taken, so you have the chance to inspect which users will
be removed before clicking the "Remove Marked" button.

Auto-mode: set property TwitterRemoveNonFollowers.autoMode to true and open
the "following" page, http://twitter.com/following
The script will auto-advance one page at a time.

NOTE: make sure you also allow scripts included from twimg.com if you’re using the NoScript add-on!!!
