HUH? How hard could it be for goggle to take say $10,000 or more and buy links from Sape sellers?
With that budget you can cover THOUSANDS of sites in one swipe. How many sxites does Sape have? Google has the resources to find it all at once if they choose to.
Even if they have a million sites what would it cost Google to buy a link on all of them? 10 million, 50 million? If they wanted to they can uncover it.
Thing is Sape will spring up the next month with new sites, so for a time Sape would be hit and just like the rest of us they have to walk away from the hit sites and rebuild.
It will alwyas be cat and mouse. As long as links are being sold, Google has the money to simply buy links to discover a network, which means its will be a constant battle of build it, get destroyed and rebuild again...
