I guess that my general impression of Yelp is that anyone can go on there and say anything they want about anyone with no vetting process in place. I'm not saying that a client shouldn't have a venue to voice grievances or concerns about a therapist's professional abilities, but say for example, my ex wife went on there in an effort to take me down and hurt me professionally. She could theoretically get dozens of her friends to write fallacious reviews of me as phony clients. Are there any safeguards against this? On one hand, it could be a great public service and on the other, there are many ways in which it could be abused. I've heard some horror stories about how restaurants have had their own employees go on there and slam the competition.
