I'm always amazed to see how people are able to program bots that can outrun or read these captcha's. To bad they don't spend their talents on something more usuable. This botwar (nor here, but everywhere) is getting out of hand. In some places I registered the captchas were already so much complicated, that I hardly couldn't read them myself and needed several tries.
If you are looking for a good one, I saw one that I found actually very genial
Example : It shows 3 Persons.
One Ski-Driver, one Bow-Hunter, one Fisher. In each silluette are 3 letters, and the question is :
What is written within the Ski-Driver ?
Sounds too me like something that is hard for a bot to break (unless the bots are outrunning the graphical part)
