Of COURSE it's necessary. We live in a world of bots and automated registration that only leads to spam, spam, and more spam. If they didn't require captcha for all user-agents, then someone could just spoof the user-agent header to pretend like they were an iPhone and make 10,000 accounts.CharlieTue, 19 Aug 2008 09:51:15 -0000
