Thank you for all the informative and helpful information. Obviously I was clueless. Now I'm not. 
I'm white listed by a provider for whom I gave an excellent review in 2014, and gave a very good review last year, but mentioned she'd gained weight. I'm sure she didn't appreciate that.
Her white list for me is still there. Is this something that can be removed at the provider's request?
Because it's a freaking lie!
I have anyone whitelisted. I am very picky about it. Have to have seen the guest several times, and the white list only stays up till a year after the visit. Otherwise I want to make sure ladies contact me for a reference so I can confirm it is still that same guy, phone #'s match/emails and that sort of thing. To many try to share accounts and even email addresses, so I want to make sure the ladies stay safe by making sure it is actually the guy I saw and not someone trying to use that to see them.
I had one long time client that I have recently stopped seeing because of his bad behavior and took him off of my whitelist. Needless to say, he was not thrilled.
A mention of a little weight gain may or may not warrant for her to exclude you off her whitelist, but if she does, then you will know why.
