I'm not saying she hasn't a right to decide what criteria to use for White Listing, but it sounds like she is using the White List to coerce (That may be too strong a word.) you into seeing her.

I have many White Listings most from gals I've only seen once or a few times.

It shouldn't take more than that to assure her that you are a person worthy of being White Listed which means that you are basically an honoable and worthy client.

links her TER handle to her provider profile. It's limited to allowing her to read only her own reviews in full. Until she has gone through the process of being granted that, she can't whitelist anyone, no matter how many reviews she has.

After I saw one of my first providers who I thought was active on TER, I asked her if she would whitelist me. She told me she doesn't do that, because she doesn't use it for screening, but she could do better and vouch for me on Date-Check. That was my introduction to verification sites. I've never paid any attention to whitelisting since then.
