  Actually I didn't, this is exactly why I wrote 'big part of the
problem' (that maybe you missed). I thought a very big percentage was
related to only bots doing the spamming, and just a smaller percentage
hiring real life people to spam for them or just solve the captcha-like
challenges (in which case the Turing test isn't a solution).

  Yep.. I repeat. 'Big part of the problem'. Which is nowhere near
'singularly successful solution'.

Let's suppose 20% of that spam you see is posted by people doing this
all day, getting paid for it. It's probably much less, but this is all a
guess, nothing more. Would it not be a solution for the other 80% ?
  Of course, if you have some statistics that tell me I terribly
underestimated that overestimation of 20%, or just introduce new
elements that I did not consider, do not hesitate to show it to me, I'm
happy with accepting facts.
