Sweetie, 'Premium Memebership' means absolutely
nothing. All it means is he either (a) owns a credit card (b) can write a review. It's nothing but a title, and premium members are no more important than anyone else. Also, cops do NOT have to say, "why yes, as a matter of fact, I
am affiliated with law enforcement!". They are not obligated to reveal themselves when you ask.
The only way to stay safe is to screen. Check their references each and every time, even if it means you have to wait a day or two to hear back from the ladies he refers you to. You cannot cut corners in this business.
Unfortunately, because you are new, you are going to run into more problems. But if you stay vigilant in your screening, things will fall into place and the bad guys will move on to the next lady. Hang in there!
