I know I'm late to this conversation, but I just had a bad experience with a masseur I found on RentMasseur, but when I tried to post my 2-star review, they rejected it (claiming I never saw him).
Even after I showed them pics of their own site showing me initiating phone (SMS) contact, twice, and even sending them pics of the conversation, they won't accept my review.
So, I wonder if there would be some way to review or alert about whole sites? Because right now, RentMasseur has lost all credibility in my eyes, that their reviews are meaningless.
