I don't agree with this. There are good and bad people of all genders and the bad will use forums and review systems to shout their bile where ever they get a chance. Unfortunately the review system is a little more personal than most, when you compare to reviewing a hotel or ebay for example. The fact that most buyers of sex are male makes it look as a collective misogynistic, but if you look at the reviews as a whole you will find that the majority of reviews are gentle, complimentary and high praise in most cases, with a minority that get the result they want by being reacted to and often used to label everyone else involved.
No one has to do anything they don't want to. No one has to see a high volume of clients in order to survive, in fact the ones that really need to survive likely see a lot less than those working towards buying a house or paying off a high loan, because they live day to day. The decision to do that is their decision and if they feel they have to offer more than they do to get clients to come and see them, then there will likely be a back lash.
This also does not account for the many, many clients who have had a bad experience and chose not to write a review, because they do not want to harm anyone's business or do them harm in any way.
In total I have getting on for around 300 reviews and there isn't one that made me feel degraded or oppressed and many of them made me smile and happy to have enjoyed time with them.
With regards to the forums and posting. There are a few small minded men that have big mouths that take things over on here and when you come across that it can be very off putting. Me I hate injustice and I hate prejudice and I work by offering the standards and respect that I would like to receive, so when someone tries to defend themselves by suggesting that I am sloppy or a man hater in someway I get upset and move on. I don't need that crap, especially from people I have never met, so no point in feeding the animals. I have also noticed that the guys that were good for a bit of banter and fun often quickly move on and stop posting, because they get picked on and it's such a shame, as I have encountered some lovely guys on here that have really made me laugh, but alas they pretty much have all left or just stopped posting. The fun has gone.
