Another site with escort classifieds of Argentina hookers in Buenos Aires. Rubro 59 is used as a number in print classifies for "miscellaneous contacts" that are mostly used by hookers advertising their discrete sensual services and massage parlors pimping their phone numbers to potential first time visitors. Now, you know why 59 often pops up in reference to escort malls. It's not that they mispelled it with 69 LOL.
