Even though you have white lists there are still providers that want references. It's just the way they operate and they won't change it. I'm fine with that. Everyone has to do this the way they think best for their own comfort and safety. Like everything else in the hobby different strokes for different folks. Your white listing isn't in vain. There are providers that will use that as part of their screening. It can never hurt to have as many things as possible in your favor when attempting to make an appointment for the first time with providers.
I'm wondering too if possibly some of the providers you are contacting don't know about TER or white listing. That could be an explanation for desiring references.

Also just like the guys say only see well reviewed providers I'm sure the ladies say something akin to that about references. Then there is a discussion about how many is well reviewed or how many references is enough. If you only have two white listings and the provider you want to see doesn't know one or either of them then she is likely to want something else.

I wouldn't be concerned. Being white listed is a good thing. You obviously had no trouble getting references so just hang in there. Get more white listings and more references and things can only get better.

I would have to agree with the gentleman who responded.  This is the first I have heard of whitelisting and I am not at all familiar with how it works.  I am always looking for the least obtrusive method for verification especially for hobbyist.  Could you please explain what this is so that I am more familiar and thus begin to offer this method?

Thank you,
