There is also a pro and cons to this reviews of masseurs. People could misused it to either spread bad rumors because the masseurs didnt want to do what the client wants eventhough it is not a normal requests, for example, some weird fetish thats beyond his boundary. I.e, using the chat as a threat. Other masseurs can also use it to gives fake bad reviews of popular masseurs.
Also, when a particular masseurs keep getting good reviews, its becoming very hard to book his service, and if the masseurs didnt limit his customers per day, usually, his service quality also tend to drop.
Personally, i always takes the reviews of particular masseurs as personal experiences and your miles may vary (ymmv). Ive a case where ive had great time with a particular masseur and become his regular while from time to time ive seen bad review about him being mechanical, not friendly etc. and ive also had bad experiences with some masseurs that people kept giving good reviews.
On the other hand, i am for sharing objectives stats about a masseur, such as physical traits, actual looks vs photo, what he will do and wont do, role, orientation, and especially rates.
