What does Google have to gain from this spammer? They do not have adsense on their sites, correct? Nope – Just checked, so no revenue for Google there.
The are making the SERPS look like crap. Does this make Google happy? Nope – they want the best fit SERPS so that other sites/SE’s will use their search algorithms (so that they can make money via adsense)
So – Google has nothing to gain by letting this go.
However – Google is NOT a small entity anylonger. So, just like any other large, bloated company; it takes time to figure out and implement a strategy. They WILL remove this spammer, but the problem is this:
If they remove all re-directs to that website, then this spammer will create SEOEXP2.INFO and continue on.
It’s not as easy as it seems, I think, and the big G probably wants a more permanent solution to this exploit.
Just a guess, though. In the meantime? It sucks big ass.
That’s it in a nutshell.
