Name change almost always signifies that something is wrong, and it's serious enough to warrant a new identity. It boggles my mind that so many guys do this without thinking, assuming it will improve their situation, and nobody will catch on. Maybe it does improve, for a minute. Just goes to show, totally reinforcing the notion that few in this business take this work seriously. Let's throw spaghetti at the wall and see if this works.
Other than massage guys pretending not to be escorts, I don't know much about the escort world. However, I get the impression that most would prefer not working, unless the client is hot, or their type, or very wealthy. Personally, I can't imagine having sex 7 days a week, let alone twice a day with different men, especially with guys I was not attracted to. I would tire of that routine quickly. So I'm not buying this.
I think it would be very difficult for a fraudster to create a boatload of fake reviews. Plus, I think many of the usernames are known individuals. Now may be a good time to try him. Sometimes it takes a little bad word of mouth to motivate. In the service business, it's so easy to fall into a rut. We can all benefit from a jolt every now and again.
