As I reported at Search Engine Land last week, Yandex has penalized link sellers in their latest effort to fight efforts by link spammers to manipulate their search results.
Yandex has penalized hundreds of link seller web site's TIC score, similar to Google's PageRank, in part of their AGS penalty algorithm.
The AGS algorithm specifically targets link sellers. Yandex also has an algorithm that targets link buyers which is named Minusinsk.
Supposedly, several hundred sites were penalized in this latest update, including large ones.
In March Yandex dropped links from part of their algorithm and then brought it back in April.
