Here in the USA there has been a steady reduction in what is available via BP. At first, BP shut down the adult sections under alleged pressure from the gummint. The ladies moved to the dating section.
More recently, ads on BP only have pics and phone numbers.
I wonder if , even though prostitution is legal in HK, BP has decided to cut access to those pages for US surfers.
