Hell Yes it certainly can. I have been in the hobby on and off for around 6 years. All of my reviews were decent ones, they all were yes. Some mentioned my mommy belly, and of course I take that as a not so good one, but all and all they were good ones. I had moved to San Antonio after taking about a year and a half off. The last review I had was in 09. I believe I had a few good ones in San Antonio before the bad one. Since the bad one came out, I have had nothing but good reviews...But....Once the bad review came out...It seemed like the whole city of San Antonio black listed me along with the providers there. The bad review headline read...something like...Babylee and her PIMP..hell no!!..
The fact that what he was saying was a complete lie had nothing to do with the clients thinking I was a decent person and a good provider. It had to do with OMG she has a pimp and the law was called. I don't have a pimp...never have and never will....and HE (the client) is the one that called the police. So yes....one single review can put a halt to your biz. I since then had to move from San Antonio and start again back in Dallas where people knew me and how I am. San Antonio never gave me a chance to prove anything. Even when i came back and tried to see a few with a friend of mine. She is also a provider and answered a call. She was talking to him and said "we" did this and "we" did that. Big mistake on her part when she mentioned my name as the other person in "we". He told her that he would not see her because she had dealings with me. Something else was said to another provider that if it was them...that they wouldn't mention my name at all..because it would really hurt their biz. San Antonio missed out on a great provider. Their loss.
