Spammers are always willing to pay for technological advances
in this area, to defeat CAPTCHAs.
Oh, wait, they *did* that already!! See:
Several research projects have broken real world CAPTCHAs,
including one of Yahoo's early CAPTCHAs called "EZ-Gimpy"
and the CAPTCHA used by popular sites such as Paypal ,
LiveJournal, phpBB, and other open source solutions   .
In January 2008 Network Security Research released their program
for automated Yahoo! CAPTCHA recognition. Windows Live Hotmail
and Gmail, the other two major free email providers, were cracked
shortly after. 
In February 2008 it was reported that spammers had achieved a
success rate of 30% to 35%, using a bot, in responding to CAPTCHAs
for Microsoft's Live Mail service  and a success rate of 20%
against Google's Gmail CAPTCHA. A Newcastle University research
team has defeated the segmentation part of Microsoft's CAPTCHA
with a 90% success rate, and claim that this could lead to a
complete crack with a greater than 60% rate.
