While onthelow's message was more than a little sarcastic, the point he was trying to make is that the whole reason a model or actress is UTR is that they don't want just anyone knowing they escort.  And those who have seen that type of provider isn't going to PM someone they don't know.  In fact, some of the high-end agencies require the client to sign a non-disclosure agreement regarding the girls they can provide.  

Also, keep in mind that to see these girls you need to be prepared to spend a minimum of $10K for an evening, usually more, often a LOT more; and 99% of these ladies will ONLY meet guys through an agency booking... so if you can afford that kind of rate and really want to meet the "supermodels or actresses", you need to contact Dreamgirls or Bella Models.
