All that article really says to me is ,punters gossip about shit they have seen or heard,
the brothel/prossie uses that with their own observations, to protect their own interests by tipping off the authorities
Although I believe that the more discreet brothels can help local communities,
by giving an outlet to release sexual frustrations, leading to fewer issues that are linked to sexual frustration.
But Leave the more obvious neon signed in your face brothels, for the night club, party areas.
