I think they're confused about the purpose of such things.
I like the ones I've seen lately that have you answer a question, like "what's my first name?" or "5 + 9 = _". I think this could have some entertaining variants like "what color is the sky?" (allow most primary and secondary colors) or maybe giving the answer to an easy puzzle.
