I can not think of a single day, except deep in the mountainous countryside, where I have not been approached by women selling themselves, or guys trying to sell me 'sexy lady massage'. Even in the mountains we're seen roadside brothels.
If the search feature was to find quality prostitutes, then that's quite probably another issue and for some a positive development.
Though the mamasans and bar girls in WanChai in Hong Kong can be quite aggressive. Leave a hand for them to grab and you'll be yanked into the bar very quickly!!
I even take taxis from the taxi rank at the airport or train/bus station(instead of touts in the terminal/station), make a point of photographing or writing down the license plate number and pretending to text it to someone, so they know scamming or stealing from me won't work as well. Never really had a problem and try to make a game out of it, so its less of a chore.
