Ah yes, that explains why in Western-Europe countries comparable polls give us at average a 32/34% (TOTAL) believer percentage. Why would you feel obliged to answer a poll in a fraudulent way if it's anonymous, no-one will know how YOU actually think about the issues unless you believe a supernatural being that can see and know all knows what you answered in which case you are actually a believer and the poll result is correct.
Most of the spammers who circumvent captcha's use real people to fill in their captcha's for them. How they do it:
1) A pay-per-filled-in-captcha site (where members solve captcha's, not really getting paid eventhough they think they will be) OR a high traffic site (false/scam sites, hacked sites, etc)
2) Mirror the image from the site you want to spam to your own site
3) A person visits your own site with the mirrored image and solves the captcha
4) Mirror the answer back to the site you want to spam
6) Profit! (literally)
