I have been following a couple competitors and they have bought links from a no 1 ranking site (not quite a competitor). It was a obvious as day that it was a paid link. So I emailed the No. 1 site and concurred those links were paid and if I wanted my link there it would cost $400 per month! I never replied. It basically pissed me off so much that my hard work all these years were being chipped away but my competition willing to buy links. I submitted a report on link purchase and sale to Google 3 times 3 months ago and never got a response (even though I mentioned I had proof and to contact me) and the competition are still climbing the serps while other sites are dropping.
So does anyone know how to end this unfairness? Google says they care but haven't done anything about it. So should I go ahead to buy links too since it doesn't seem like it is illegal if there is no penalty?
