I thought about posting my views along similar lines but figured the backlash wasn't worth it, but since you opened the can...
It really is against Canadian values too, and seem to even go against what even the ladies want. They want sex work to be legalized, or at least decriminalized, and to operate in a free market within a free society, and for them to receive all the benefits and rights that other workers receive, right? Well, reviews are part of a free market in a free society now. If you would like to control what people can and cannot say about their own experiences, I suggest you live in a country where free speech is not valued, like China. If you don't want people reviewing your services, don't provide them to the public. Not to mention, reviews practically run markets now and are a main factor in consumer decision making. Ask any advertising firm. Reviews matter and people should be able to review whatever they want, within reason, in a free society. Reviewing an escort on an escort review board seems reasonable to me.
