And quite a interesting challenge as even introducing something like a
time limit to enter the captcha would make no difference .
Stopping the spam bot from grabbing the chaptcha image (and using it in
the strip tease app) would appear to be the only way to beat it .
Displaying several captcha images with a human being able to pick out
what one should be used is easy enough - but even that would only cut
the amount of sucsessful spam bot entrys as the spam bot would grab all
the captcha images and give a different image to different users .
