And then fails. Anyone managed to do this, or have any other advice for using Recaptcha from perl?

Please don't use it as a barrier on the only access route to a
service, else you will be locking out humans with vision or hearing
problems, or even simply high browser security settings.


Does anyone know anything concrete about "cognitive" captchas? I've run into anecdotal support for things like:

  Enter the word "orange" <input name="foo">

Or:

  Enter the number that answers: How much is two plus
  two? <input name="foo>

Or even:

  Leave this input blank: <input name="email">...


Are these known to work? Or are they just clever guesses about what bots might not be able to figure out?
