I'm not sure, but what Z might be referring to is the absence of Alex Bald's recently posted crux videos. Up to today, when you searched "crucifixion" at C4S, you got mostly AB crux vids until you got to page 3 of the listings. Now most of the recently posted AB ones are gone.
My theory on this is that C4S doesn't like one studio to monopolize its listings. AB told me this one time when I asked him why only some of his works were offered there. The other vendors complain, and C4S takes down much of AB's stuff to keep them happy.
It doesn't keep us happy, though. (insert frowning emoji here)
