what is this ad really for? a roommate? or a partner?
if you open the ad up, it explains that she's looking for a bodyguard - and asking them to pay $50/week to be the bodyguard. even if you include rent, that's still only about $75/week paid out in exchange for a premium service.
of course, the sad reality is that this woman is almost certainly going to get raped by the person she's "hiring" for "protection".
but, what i find more interesting is placing something like this in the context of the marketization brought on by neo-liberalism - it is the conversion of what has generally been considered normal relationship duties into a service to be traded over a market.
