OH I agree that it is the main reason for TER and what not.
The main reason why I come here is to make sure they are not a scam. Which i dont understand why the moderators dont understand when you talk about a scam they dont post those reviews. The other is possible services they offer or dont offer. That why you dont need to get specific in communication via text or anything. Then you dont need to have an ackward convo that can throw off the mood right away. IE: you know if they do those services or if they dont going in.
Also if the apperence is moderatly the same or not. DEPENDING if your doing "agency" type asian, latino, etc. OR if someone has aged, gained weight, etc.
I also know chemistry is a case by case situation. But many dont think this way at all.
But that is why a standard rating can throw things off. Like mentioned per looks my 10 can be your 3. My idea of a 10 in performance could be someones elses 2. That is why the typical "standard" scale of 1-10 is off.
IMHO should get ride of that type of scale. Just do services rendered type thing (just like they have know the "check boxes") and then talk about how the experience went. I know some like to write novels to make them seem like the next porn star in the making. While others are more down to earth.
One thing I wish that TER would add in to the reviews for each individual one is a time length. IE: did you see the provider for 30 min, hour, 90, over night, etc. It could help others know what to expect as well.
