that just gave me an idea...
wouldn't it be even more difficult for a (future) bot if the text of the question was written in a image?

the bot thinks its a normal image.. and... writes the question text instead of the answer..

so we know its a bot and not a stupid user.. and he can be automatically banned without risking to ban a normal user..

example:
question: HoW much i s two and 2?
written in verdana font on a transparent gif. A user will think it is normal text..
A bot will think its a captcha image... and will enter the text as written in the image ..
so if he writes it exactly (with spelling errors, typos and strange capitalization,
but not respecting the spaces in the sentence)

.. we know its a bot.. (even a "not so bright" user will at least add one space in the sentence)
