There's no TER requirement that a review is required for a whitelisting.   Only that, in your opinion, the client is a "good guy".  If it's your position that submitting a review is required to be a "good guy", that is, IMO, rather lame; but it's your decision.  

Cheers!

I view whitelists the same as I view p411 oks.
So I would whitelist someone if I have seen them and everything went ok.
Men don't have an obligation to review... Just to show up on time, be respectful and leave shoe money.

It depends how you view whitelists, but I would not refuse one because someone didn't write a review.

Without writing a review.  I usually don't bring up reviews at the end of a date, so I don't ask for a white list reference.

I don't have the heart to hurt a lady's business unless she has it coming which is rare so I have chosen to NOT review more than reviewed. However not all unreviewed whiltelists are for that reason. SOme white listed because they felt I was worthy regardless of my commenting upon our session

Admittedly I can be a bit verbose, lol.

I will send a review to the Lady soon after the date, even if I already have one posted here on TER for her.  

Since I like the connection aspect when meeting, and I meet with ladies who are more than "wham bammers" themselves, and are really intetested in sensuality, each encounter is unique. I want to share how that uniqueness impacred me. I always give them the option of keeping the review private (and some have chosen that), as well as asking if they want me to submit it as an updated review if I had already posted for an earlier date (and some have chosen that).

Personally, I would not ask a Lady to be a reference without first presenting her with a review.  I chose to see her in part because of what others wrote, so I want to return the favor.

Since I try to stay UTR I prefer not to write reviews. My choice. Furthermore, many times I have been asked to NOT write a review (many providers do not want to risk a lower review score which could possibly also lower their current TER rating). Since I have encountered these mixed messages before, I don't know if the provider wants a review or not and I don't ask or discuss and it has never been an issue. If a provider tells me that I must write a review in exchange for a reference I would simply elect to not ask that provider for a reference.

I never ask people to write reviews. If they want to they will. I see hobbyists that just don't write reviews. I know it is a double edge sword. Many read the reviews written and based on those reviews will pick a provider (and they won't write a review.) Others do searches on certain criteria and will choose based on that alone. I have had some tell me they picked me because I didn't have a ton of reviews. I white list those I have seen that I would see again. I appreciate every review I have gotten and reviews are welcome but not mandatory for me to white list someone.
