Yandex war with optimizers like Runet engine

It's no secret for anyone in SEO that Yandex is not friendly with optimizers, it is at war with them. Both with black and gray (there are no whites). For each attempt of SEOs to push their sites to the top, Yandex responded with punitive measures, sanctions, filters, pessimizations, exceptions to the index, and the like.

Once on top of popularity were linkators, directories, xss-vulnerable sites, snouts. Now in fashion purchase links from the internal pages through various exchanges. Resource owners, who learned about such automated brokers, rushed to place links on their pages, began to receive the first profit. After all, there is nothing very terrible when the owner places ads on his website - everything is quite logical. But human greed knows no limits, hundreds began to appear "zero" resources, made only to sell links. Calling them sites for people is extremely difficult - they are primarily for robots and for optimizers. And this situation suits both webmasters and SEOs - both sides found a convenient and profitable option for themselves. Only Yandex was dissatisfied and, as usual, began the struggle, arranging demonstrative imposition of sanctions, which often included quite useful resources.

The result of this struggle is not yet clear, but how do sites for sale breed with a snowball, and they multiply faster than Yandex manages to filter them. It turns out to be a hopeless situation - if you filter the link blocks, the link ranking will undergo significant changes and the issue will become inadequate, and if you do not filter, the Top-10 will become an auction, which, in principle, is now, except that the money from this auction by Yandex cash register and how he will solve this problem.
