The sales people don't have access to the content moderation systems. As far as it showing up in code, I was just making the point that there is no file containing something like

  if business_has_paid_extortion_money:
    show_good_reviews()
  else:
    show_bad_reviews()

... which is how people seem to think it works.

There is also no code to allow manual review ordering. They are sorted according by an algorithm with a variety of inputs including who you are friends with, who has Elite status, etc.
