Not that I agree with it, but the premise is this...<p>- reCaptcha presents 2 words for the end user to solve<p>- the purpose of the second word has nothing to do with security.  The word itself is not known to Google.<p>- the &quot;fraud&quot; is that Google is deceiving you into helping them decipher the second word for their own financial gain<p>(paraphrasing from <a href="http:&#x2F;&#x2F;digitalcommons.law.scu.edu&#x2F;cgi&#x2F;viewcontent.cgi?article=1904&amp;context=historical" rel="nofollow">http:&#x2F;&#x2F;digitalcommons.law.scu.edu&#x2F;cgi&#x2F;viewcontent.cgi?articl...</a>)<p>Edit: Please note that I am not in agreement with the premise above...just trying to summarize it.
