I am convinced that this has become a lost cause. Crafty spammers will ALWAYS beat the search engines to the punch. This guy (SEOEXP.INFO) realeases sites in a dribble fashion over time, to always replenish those that have been eliminated. Even though he is a skunk, he is a crafty skunk, and I’m afraid to say, he will always win.
I don’t believe the Search Engines have enough negativity at stake here, to combat this, especially since there is Adsense revenue in the mix.
There is a reason for everything, and I cannot believe that the Search Engine designers could not have come up with automated checks and detection to prevent entry of this spam into their indices. Like I said, there is a reason for everything.
Maybe it’s time to go back to work and get a real job……
