Sorry, Anna, but these rules aren't worth the paper they aren't printed on. The sad truth is that if a cop wants to arrest you as a prostitute he can do so on NO EVIDENCE WHATSOEVER, because even if his jurisdiction requires more evidence than most he'll simply lie. In various parts of the US a woman can be arrested as a prostitute for carrying condoms, being in certain places alone, not wearing underwear, winking, "acting sexy" or (in Florida soon if a new law goes into effect) your suggestion #8, asking if they're a cop. And I guarantee you it will stick in court.
American "feminists" have sold out other women to advance their wrongheaded campaign against men; that's why they don't protest these practices which allow any cop in this country to arrest any unaccompanied woman anywhere for the "crime" of being female.
