Thanks for the reply chuck. I totally agree about the spam pages filled with ads and no content.
What sparked me to ask this was a post I recently read on
Matt Cutt's blog about reporting of paid links. He is head of Google's link spam team, and it looks like they will be starting a war on paid links. Quite arrogant to believe they can control the market like that, but still.
As you might have guessed, I'm very much in favour of the free market, and of paid links! If you read all the comments on the blog post mentioned earlier, they are at least 10:1 in favour of paid links I'd say.
To cut short what may otherwise turn into a rant - its funny how Google's search placement algorithm is 90% based on links (numbers and quality), and to compensate for that short-fall they target the people trying to legitimately pursue capitalism.
