I've noticed that some providers ask to be provided with references. How are they aquired?

Hey sugar daddy..
Love the name your my favorite kinda candy!

Ok references. If you have never seen a provider you obviously are not going to have any. She is asking for names of other ladies you have seen to make sure 1- your not wacko and 2- your not LE

If you have no references SOME ladies will not see you. Others will ask for you to provide one of the following:
a date check secret keeper or RSK2 Member ID -
work information to validate you are who you say you are
a landline that is listed not private and some othe info

When we seek this info its not to abuse your privacy in any shape or form. It is to conduct a little exchange so that we can be assured you are A-ok

I am new at this and I appreciate your patience.  What does "LE" mean?

Thank you
