There are also "prove you are a robot" schemes, like proof-of-work.

  I did a job application once where as part of the application you had to solve a simple math problem that was displayed at a specific URL[1]. The catch was that the math problem was different every time and expired in half a second, so the only way to do it was to script it. I guess its a time-based proof of work kind of thing. [1] IIRC, the URL would give you a simple arithmetic formula to solve and you would hit another URL with the result, something like /foo/<result> and it would give you a code. You then included the code in the application.

    That's perfectly automatable, but I guess no one took the time to implement a robot for it.
