Yup, very, very low paid human behind that methinks. Jeff A. wrote a post last 
fall about captcha Turing tests that confirms what I have found anecdotal 
elsewhere - add a bit of noise to your captcha and OCR is beat. IMHO, he's 
slightly off on the economic model wherein the humans are paid $5/hour, think 
it's more like USD $5 day but that still is enough to break the bank.
