Scarecrow: Ad Blocking Script for Twitter
by Stuart Robertson on November 3rd, 2008 | Social Media
Magpie is a recently introduced service that inserts advertising into a users list of posts on Twitter. Scarecrow is a greasemonkey script that will stop these ads being displayed on your view of Twitter allowing you to “opt out” of the service. Other users have suggested simply unfollowing users who use the Magpie service, but I think this script gives people another option they might prefer.
Installing the script
1. Download and install Greasemonkey for Firefox
2. Download and install Scarecrow to stop Magpie advertising from displaying at Twitter.com
Nov 21, 2008: Scarecrow 0.2 now available – updated after changes in code at Twitter.com
