This is mostly for reviewers. Have you ever received any kind of hateful PMs after you wrote a review of a provider

Motherfucker I'm not a 9! I'm a 10!

Only once, and not truly hateful, just kind of whiny. She wondered why she didn't get a 10/10, which I suppose she could have gotten, but the score I gave was plenty high. I rebooked and then she canceled on me with no offer to reschedule, so I guess I knew where I stood.

First of all "bad" for me would be a disaster which I have not had happen since becoming a pro at this.

several times after mentioning obvious (to both parties) issues gently, even with good scores.  My reviews are generally generous.

If you don't then your approach is fair. If you do read them before you book it is very hypocritical.  

A work acquaintance who also sees escorts (he's actually the only one who knows this fact about me), showed me text messages from a recent provider who blew his phone up about a poor review he left for her (No, I'm not giving out his TER handle

A traveling provider. Had my usual single pop. While we were talking, she kept playing with me and I was cool with that arrangement. She asked if I was up for another go. Since I had woken up already and she offered, I said yes. After four or five minutes of getting it on, she shut it down and said our time was up. I said that this was your idea and that had I known it would have been a less than five minute soiree, I would have declined. I gave her and 8/8 score. She was very mad sending me PM's for several days. I thought my score was very fair and was about her average. I learned you can't please everyone. I normally give anyone I am with the benefit of the doubt and I always round up when I am debating what score to give.

good review.  Sometimes it can be a mutual lack of chemistry, etc. that impacts the session.

Do I read, not so much.
Do I look at scoring consistency and the fact that she has reviews, yes.

I saw a provider a long time ago she wasn't the girl in the picture and i felt other guys should know. She was still good looking had a great body and we had a really great session and i put all that in my review of her. I did however say she was not the girl in the pictures on her site she was so mad she sent me several pm's and emails asking me to change my review and take that out she said she was losing business because of what i wrote. She actually demanded me to change it i said no my review of her was very good and fair and guys deserve to know i said put actual pictures on your site she got really mad at that but finally stopped messaging me.

...from other hobbyists who agreed with my assessments or appreciated my candor. I have never received any responses to negative reviews from providers.

because she thought it was too graphic. She said I could post it on ___ [can't name site] which I did.
