and later receive retaliation from provider for saying that?

Done it once were a provider kept on calling my cell phone demanding me to take down.

It depends on your definition of poor.  I have had four providers contact me regarding reviews.

One asked me to delete it. I think she was dissappointedd that I didn't give her a 10 for performance but to my knowledge at that time she did not provide enough of the services to warrant a 10 (none provided to me nor where they discussed in other reviews nor where they in her profile). On later dates she was willing. But the main complaint I think was a comment about smacking her ass. She said every spanking fetishist was calling. So I edited that part out for her because it wasn't a major part of our day just a couple swats for exclamation.

Another lady was also hoping I would upgrade to a 10 for performance but she definitely doesn't do the extras. She's quite a princess and she is gorgeous but eventually she pulled her reviews from TER because she wasn't getting 10s.  (Are 8s and 9s really that bad?)

A third lady was a nightmare date. She was fugly. I was very upset because she sent me a photo after I questioned her blurred photos on her website and the new photo still misrepresented her.  I actually was very nice to her in the review but she still hates me. I even got an email a year later from her - she still hates me that much.

And then one of my first reviews got me an email from another hobbyist saying that this lady wanted me to call her regarding the review.  I was new to this internet hobbying and didn't realize how much photoshop editing goes on nor did I understand the distinction between BBBJ and BBBJCIM. In my world I thought if it's not CIM then it's just a BJ leading to a HJ so I only gave her a 6 for performance.  That's the only review I would ever change in hindsight. Angella Masters in LV is really a7or 8 in looks and a 7or8 in peformance you just have to realize there's no CIM.  The caveat is that I grade realistically in looks.  I think we hobbyists get caught up in the ecstasy and confuse pretty girls with "model material." There's a big difference.
