...why? Once my agent has a key I, the human, can also use it. And surely any human use would be less intensive than any agent use.
But once a human has a key his agent could use that and people still like to use ordinary CAPTCHAs.
Right - perhaps title could be "prove you are an robot, or have access to one"
Because now you know their company exists!
Exactly. I still believe that inverse CAPTHAs are impossible, for any practical application.
Is this just a marketing stunt?
