Is it possible to search for reviews without being a member?

It is, but it's limited to 2-3 reviews only. 

Should i take those reviews on uk punting for granted? 

I reckon 80 and more percent of reviews there are real. They use the adultwork platform as a kind of validation that the meeting had really happened, and i think that is the strongest evidence they could provide besides the actual porn video or photo data of the session.

How the hell can i search properly on Ukpunting?

I am searching for a models reviews,i know she had many and i can only find 1 review

Can anyone help?

Just google escort's name and uk punting and it should list the reviews. When you open some of the uk punting reviews, there should be a total number of reviews next to escorts' name, and when you click on her name the list of her reviews should open in another tab. Maybe she really has only one review.

Thanks mate for your reply but still can't find. I read that has many reviews

Could you please also search: Caroline from Black Label London and Spades of London

Thank you

I found only one review of her.
