Inside the precision hack. How 4chan members subverted a Time.com online poll to reorder the options and spell out their own message. Partly poor application design from Time (the first version used a GET request without input validation), but I challenge anyone to design an anonymous online poll that can’t be fixed using the more sophisticated techniques 4chan eventually deployed based on HTTP proxies. 20th April 2009, 8:36 pm
