That's what I do, but it requires a mod. The text questions available for custom profiles have no mechanism to flag a wrong answer, from what I've seen.
You could use the number field. Tell them to type in "33" for example. Then set the minimum and maximum options to 33. Then registration will fail unless the bot or human enters 33. Failure to do so will give a prompt telling them the minimum or maximum, but the bot has to be programmed to read the promt and respond accordingly. Not likely yet.
