Hi,

if I want to attac a special machine, I still can do that with a few
regular expressions of perl, even if the grammer and the numbers change
within a small range by accident. The range is limited because your
computer needs itself to understand it to produce the result.

If you provide a catalogue of questions like "capital of italy" it is also
limited so that questions occure again and again. So it is possible to mass
attac this easily.

ASCII based questions of this kind can give a better protection than none,
but they are fare behind a real captcha.
