The thing is though, for anything small scale a simple "Type Human" in a box is 100% effective for the random spam bots. For anything like what you are experiencing you are being targeted so even with the best CAPTCHA around spam is still going to be a problem.
I honestly believe that CAPTCHA's are one of the most evil things on the internet and that there are many valid and better ways to avoid spam.
BTW im not just some random guy with an axe to grind over this, I wrote http://www.wausita.com/captcha/ as an example of how trivial 90% of the CAPTCHA's on the web are trivial to decode.
