True.
The class I mentioned was written specifically for an online game that uses
this type of "human-detection". What it does is filter out most of the
quirkies put into the image to make them hard to decypher, do a remapping to
a smaller b/w image and then perform a simple OCR. For the site it was built
for, it's about 90% accurate. In the other 10%, the site won't accept the
registration (in which case the script simply tries again).

I think using this technique (and doing it properly) will scare away most
script kiddies though.
