I think the link sellers are always a step ahead of Google and will always be. Google plays whack a mole all the time and their algorithm constantly changes as we all know. The sad part is that when Google changes their algorithm it can have unintended consequences to the sites that do not buy links. I think recent changes might also explain why big brands have been rising to the top of the results.
