Then ask...

IMO, its not worth it for several reasons:

1) It may pressure you to give a better score on your review then is accurate.
2) It verifies your review...(remember, the review is supposed to be a fantasy)
3) If you post on the discussion boards, it fucks with your anonymity.

Other people have their reasons as well.

I have whitelist turned off, and will no longer give out my TER handle. Instead, I use a verification site and see ladies that are on there. P411 RS2k P411...take your pick, whatever is used more in your area. See the ladies that advertise there.

TER is great for back channel communication, and for you to get a better idea of the provider you are seeing...but for verification...most ladies don't use it anyway.

This link will answer all your questions.

From your reviews, the only lady able to white list you is "Paige / Nichole" because she has an account linked to her reviews. Unless you've seen other ladies who have an account here.

Providers will generally white list clients that they have a strong connection with, feel safe with, and somewhat trust. Usually this is after a few meetings, getting to know the provider well, etc, but can happen after one encounter if she feels you deserve one.

Keep in mind that some ladies don't white list at all for personal reasons.
If a lady you've seen is still willing to be a reference for you, that should be good enough.
