I think a lot of people do not know what happens. I know someone that used to send traffic through blind links with a picture of a woman saying "click here for more of my pictures".
He used to get emails - ONLY ONE figured out he was "scammed" (and was very displeased let me tell you) the rest all though the link was broken - even though it led to pop up city.
It would say stuff like, "Samantha, I tried to get your pictures and the link didn't seem to work - here is mine - please send me yours." He didn't get a whole lot, but somewhere around 50 or so would be my guess.
The average surfer doesn't know what is going on.
Google gets:
5,800 searches A DAY for google.com
29,000 searches A DAY for yahoo.com
That should tell you something
