I am willing to bet (but not to spend my time on this) that of all these backlinks probably at least 40,000 are blackhat sites. And I think it’s likely a lot more than that.
Even on the first page of google http://www.gamesandcasino.com there are 4 blackhatters. I am totally riddled with blackhatters linking to me, partially to ride on my rankings, partially to try to google bowl me.
Don’t forget that there are five years of work behind this site, and for four years I put all earnings back into site development, not traffic buys or my pocket.
I see links as a limited resource. Every outbound link depletes this resource. Linking out to inferior sites just to get an inbound link is not recommendable in my opinion. It will give that boost one wants so much for a fledgling site, but it is shortlived success.
If I had a new site I would probably temporarily link to many sites, take the time to make sure they are quality (not high PR but high quality) and once the benefits show I would start cutting down to less and better links.
In the long run, it’s quality and not quality.
And I have always been in it for the long run.
That said, I have a complete review of links on my agenda, and I will likely stop some exchanges and add some one way outbound links.
Call me foolish, but then people have called me that all throughout the growth process.
