i really dont see the point in this rule change.
if an escort is doing gangbangs and charging for them its still escorting as far as i can see and then this is the site for it as it is an escort directory.
and as you had said a swingers site is the place for this i think your wrong as from what i know about swinging (granted not a lot) its something that some people like to do but they dont charge each other for it.
