if she likes you well enough to White List you, I think it would behoove you to write a review, esp if you enjoyed the session.

I think a whitelist after a review is posted is pretty common.  This is evidence you actually saw the lady.

Does a hobbyist have to write a review in order for a provider to whitelist or can they whitelist regardless by just searching their username somehow?

You do not have to write a review, if you've seen her and she knows your ter handle, she can white list you.

To further muddy the waters, the lady that Whitelisted me has never seen me professionally, we only met once at a M&G. Go figure.

...unless she has been in a session with him.  He could be a nice guy at a social event but could be an asshole in the bedroom.

It just seems dishonest to me, not to mention I am not the least bit attracted to the woman that whitelisted me, and I would never have had a session with her even if it were for free. lol
