I've been in the business Since Dec 08 but have never used Date Check.  What is it and how to use it?  Do I need to for my security?  What are some other secure methods of screening?

"Do I need to for my security?"
in a word YES.
Date-check, preferred 411,Roomservice 2000, or any of the others available.  Please sign up with one of these services until you find another screening method.

You might want to ask on the provider board. That way, you can get feedback directly from other ladies without going into details on security here. While I obviously haven't seen it, I'm sure there is a lot of info over there, and ladies willing to help.

Good security and safety are in everyone's best interests. Good luck.

Most people think of LE busts but even more importantly, your physical safety. From time to time you read about some provider getting robbed or beat up. In a lesser since, a unrurly customer so date-check places alerts on their file.  P411 kick you out if you have alerts.  So it save you a lot of headaches

You have enough reviews to join the provider board.  Send a note to  admin asking for access.  Additionally, I would join dangerzone 411.  They have a lot of resources on their.

But yes, join date-check and preferred 411

As far as being kicked off a verification site if you have alerts...not always true. Sometimes the money the guy pays is more important than removing him...I know from first hand experience of more than one guy who is still listed with a national verification site that has alerts on major provider only sites....that's why verification sites are but one way I screen.
