I'm not sure about the Wayfair angle, but any image search in Yandex using "SRC ______"("Name of country") or SRC kids, or SRC Ru kids or SRC followed by almost any random group of numbers will produce the phenomena described in the theory. It does not have to be Wayfair SKU numbers. "SRC" seems to be the main term to investigate along with Wayfair.

Almost any random number following "SRC" produces the phenomena. Also "SRC" followed by "Brazil", "Russia" "China" etc. produces phenomena. Not only Wayfair SKU numbers.>>9917253
