I don't really like the idea of asking questions or picking images, I worry that less web savvy folk might read it and think "What the heck is this? Why is this website asking me a silly question? What is 2+2? Or what year is it? Or pick the elephant." Even if you explain why I still don't think it looks the best, especially for certain types of sites.
Standard captchas have been around longer and I imagine more people would be used to them. Imo I think they look better than asking a silly question too.
I wonder how an animated gif or flash captcha might work, I haven't seen any of these in action. Surely they would be very hard for a bot to recognize and nearly everyone has flash these days. |
