I'm sorry but you are incredibly misinformed. As someone that has sold sponsored posts for a very long time with some of the biggest websites on the internet, I can confirm to you that it is happening at a much larger scale than you can ever imagine. For those that know, this story is not really news and has been going on for several years. Google has indeed been fighting spam and has done a decent job at it but in many cases the smaller sites are the ones affected the most and the big name sites get away with it.

"We don't know if these tactics are even working." They are working. Google is catching up but it's still FAR from being ahead in fighting these blackhat SEO practices. What you mean is that Google WON'T be saying "these guys are right, we favor big sites" but the reality is they do.

I made a fairly large comment on here with the last report. Many of the comments said "show me proof!" which then I came along and did just that. Matt Cutts reached out to me shortly after and I forwarded over emails received from Expedia. The funny thing is, a few weeks after that I STILL got emails from Expedia BUT it wasn't from Expedia.com. "Only Expedia.com was affected so we're still going to sell links for Expedia.co.uk". It amazes me sometimes how blind everyone is about this.
