Why white actress/Caucasian actress are not being casted on chikan/molester jav anymore?

Hi. I created to know why white actress or Caucasian actress are not being casted on molester 0r chikan jav anymore? I tried to know by searching on internet but couldn't found the specific reason. White actresses are being casted on other genres of jav but not on molester. Most of the jav that features white actress was made a decade ago. Please give your valuable and authentic feedback, I'm curious to know, no nonsense please and sorry for my poor English.

Ps: Photo for attention.
